Yellow wire goes to fused power. To the battery if you want to use it with key on or off. To fused ignition hot is you want it to only work when the key is on.
Hi mr Broke Bastard Garage , This job i am thinking to do is on a big rig tractor will be exterior extra lights i wonder if i need a fuse those extra lights they're going on the roof or viser & some i will going to put on the side of the truck. Could you help me with that please if i need a relay o fuse.
This is one of the best instructional videos I've ever seen! I know NOTHING about mechanical/electrical stuff but I like to learn and do things myself. Most people assume you know something and skip over steps. You took us step by step through the whole process and explained everything along the way. Then you did a recap to make sure we got it. Finally, you did a tool recap explaining what the tool is and why is needed. If there was ever A PERFECT instructional video, this is it!! I'm buying all these tools and I'm going to solder some 16 gauge wire to a 20" led light bar to use on my new zero turn mower. The mower is prewired for a light kit and has a relay and fuse box under the seat. I can't wait to get into it. Thanks for the video brother!
The fact that you solder the wire to the butt connectors , and slide the heat shrink up over the prong of the relay is an Awesome tip. Very clean. Very safe. Thank you bro
I had completely new to car electrical wiring . Bought a day time running lights wanted to install it myself . Thank you for explaining in detail. Amazing video and no crappy music in back ground just raw information. Awesome
One of the best videos I've seen on garage "clinical" skills. I did electronics school in the Navy and I always admire folks that solder their connections. Sign of solid work IMHO.
I've been watching a lot of videos on how to wire some accessories on my truck. This is the best I have seen on soldering with excellent explanations of what and how. Thank you.
This was one of the best instructional videos I have seen in a long time. Some detractors may feel this was incomplete and/or leaving out some things, but it's essentially a 19 minute video covering a a few mini-topics within the project. I never considered some of these things. I doubt I will do all of this for every project as it might be overkill in some cases, but I will definitely consider his advice and certainly use it when the need arises. Seriously people (You know who you are.), don't do any of this without adequate background knowledge and some practice if needed. Great instruction and much appreciated. Two thumbs up!
most people think they can solder...and they don't understand why the wires don't stay soldered...you brought up good points...clean wires...clean soldering tip...tin the tip of the soldering iron and the wire to be soldered...heat transfer and NO cold solder joints...great video Mr BBG...keep up the good work...!!!
I rarely comment on youtube, but you, Sir, are comment worthy!! Prior to seeing your video, I had wired my P/T Cruiser radiator fan the "wrong way" as you put it. The "wrong way" did work HOWEVER the wiring would get so hot at the toggle switch that I would have to cycle it off and on just to keep the wiring insulation from melting!! So someone told me that I needed to rewire it using a relay. Soooooo I watched many youtube videos but I was left scratching my head UNTIL I CAME ACROSS YOUR VIDEO! I immediately grabbed a white board and sketched out my new wiring diagram based on your video! I literally just got done rewiring the radiator fan and it works with no more hot wires!!! You da Man!!
Wow!! OMG!! This guy is EXCELLENT! Also, love the cat in the background at about 10 minutes in. He really does an excellent job of explaining WHY you should use a relay when adding a new item to your setup or car and what a switch, if you decide to use one, is actually doing in conjunction with the relay. His tips on wire splicing, connectors, and soldering are also very, very good.
Thanks, best accolade I can give, your an excellent instructor. Our young people don't always have a dad or one with how to, they use to. My son going to college blew the minds of his fellow students, because one, he tried to fix stuff and second he had some knowledge. Mike Rowe would love you, as I.
You do solid work. It is irritating to me when people take shortcuts to get a job done quicker and the result is a mess that never lasts long or causes other problems. Take the time to do it right the first time and be proud of your work. You certainly should be - your work is tight!
Thanks for making this video, I know it’s 4 years old. But it was helpful for me. I tend to learn in a odd way. This was exactly what I needed. To the point, no goofy music, and talking like I was there watching over your shoulder. Sub’d
Soldering tip. When you put your iron away, tin the tip of the iron. This will prevent the hot tip from oxidizing, which makes the tip wear out sooner. Good video you did.
Thanks -Your video is the first one that actually explains the wiring of a relay in simple , clear and concise details. I am very grateful as I am going to install an air horn in my car and needed a video to show how.Excellent !
Sir you'd an excellent job indoor tutorial. Very thorough and complete. I am a novice to electronics and wanted a basic intro to relays, and you provided that. Not once did you talk over my head and you explained things in a way that made it very understandable. Also you were not condescending at all. It was as if you really wanted to enlighten and educate the novices. Thanks so much. Also excellent tutorial on soldering. As I stated you did a great job.
FINALLY a video that emphasizes attention to detail in the construction technique. This is the kind of attitude that turns a project's 5-year lifespan into a 40-year lifespan.
I completely RELATE to 98%of what you had to say... i take the plastic of the connectors i solder EVERYTHING i cant stand thick solder the small circuit board wire is way easier. I have never totally understood the reason for the Relay i totally get it now THANK YOU.. I also just got back from the worlds largest Car/Truck show last week Sema 2019..
Wow very explanatory, thank you so much your video is excellent on how easy is to understand how relay and wiring works, it took me 45min to wire my electric fan with your instructions.THANK YOU
Fantastic educational resource - here are some key sections for those who like me would like to come back to it 0:23 The quick and dirty 'other' way to wire up - i.e. not recommended 0:59 Demo of the 'other way' to wire up 1:59 Discussion about the proper way to solder 14:33 2:39 Tinning wires - a key preliminary step before soldering two pieces together 4:12 Apply heat to bottom side of wire so solder wick through the wires i.e. coating all the wires 5:10 Apply heat shink if needed before soldering the pieces together 5:35 Soldering the 2 wires together 6:34 Heat shrinking 7:16 Fusing the circuit - adding in line fuse Wiring the relay 8:17 About relays 13:35 8:43 Adding connectors to wires for the relays. Interesting aprooach: removing the plastic surround, tinning the wire and opening the connector before crimping . 9:47 Only crimps to hold in place before soldering connector the wire. 10:15 Adding the power to the relay, prong #30 . Note: doesn't suggest soldering to relay 11:07 Adding the light to the relay, prong #87 11:38 Grounding the light and relay #85, options to go to the frame or to the negative wire. 12:30 Plugging switch to #86 Note: option to heat shrink unused prongs on the switch or to simply cut off note: Yellow wire should be fused if connected straight to the battery if you want to use it independent of the ignition. Alternatively, get the power source from a fused ignition point if you want it to only work when the key is on. 13:18 Demo of how the system works i.e. switching on the light 13:35 Explanation of what the relay is i.e. acts as remote switch to carries the load of the current rather than the switch thus minimising the use of heavy wire directly from the switch which can lead to voltage drops and/or overheating of wires and fire . for more about relays see this link ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UVLw9V8NiLY.html 14:46 Tool review. 14:51Soldering irons 16:03 Types of solder. Uses flux in special in circumstances such as computer boards where you want to control solder .. but suggests it unnecessary in general use . Prefers rosin core as it melts better. 16:35 Likes thin solder as it helps control application and minimise lumpy soldering 16:54 Crimpers and Snippers , get one of each. Do not get combo stripper crimpers as the crimping is too narrow. 18:23 Heat gun vs cigarette lighter
Close call , i was just getting ready to work on a relay for my riding mower ( lose wire ) at the ignition switch . Thought i would check around before i started working = Lucky i did ! Have seen a lot of videos on other subjects ( never saw one of yours before ) and i have to say that this is one of the finest i have ever seen . Your thorough and as a result , a good teacher ! Thank you ......
Most common fire on a car is electrical fire! Yes, great video! Relays also help with voltage drops, as you can shorten the power run to the load. Also, as you may already know, Relay, Solenoid, contactor, electrical motor starter, are all the same thing. Grab yourself some flux. Solder will stay brighter, and flow easier. No need to tin, if you have flux on all the pieces. If you have old oxidized (brown copper), a brass or steel brush to brighten the surfaces. Very helpful, if you have a large joint, and rosin flux that comes in solder burns off, or if you want to reflow older solder. The connector you crimped, you could coat in flux, crimp, then solder will flow into fluxed areas.
Do you go to any extra effort to clean the area (of flux residue) after completing the soldered joint? I have opted to mechanically twist the overlapping opposed wires, then apply flux and completely solder (prior to flushing away flux residue) and then cover in regular heat shrink or occasionally special lined shrink wrap that releases an environmental sealant when applying appropriate heat.
@@JonPBixby I usually clean off the used flux residue with IPA, or on a car, any solvent that's safe for the application. If it's just a wire, under the hood, I'll use a shot of brake cleaner. Inside a car or near something that might melt, I'll stick with IPA, and a rag. Nowadays I use 'no clean flux', but I still clean it. No clean flux just means it's safe to leave and wont promote corrosion.
Hey, great instruction with correct demonstration. Very good to see! In the beginning, I wondered why my swiches would get hot, until I figured out why through trial and error. Lots of errors, but luckily no fires! I'm now on my thirty-third truck of which all have been older used trucks, and I put road light, fog lights, and back up lights and many other simple devices in all of them. The parts and method you demonstrated here are all correct and the responsible way to do it. Great Job!
Thank you for getting right to it! Thank you for touching up on the soldering as well. I love this video. It was the only one I found that explained EXACTLY what I needed…and most of all, thank you for NOT blasting music during some parts. I could follow along without putting my project down to annoyingly adjust the volume. Keep your videos just like this my friend, I’m a subscriber!
Absolutely simple to follow and understand you! Thx for making this as easy to follow as ove ever heard! P.S. I used to do it "the other way" (no relays) I now see the obvious errors on my old ways! Anyhow, you've got yourself another NEW follower! Keep up the great work!!! Matt 🤘😎
I have been viewing you tube videos for years and have never posted a comment. This video made me create my own channel to allow me to list this comment, great video, you rock at explaining things. Cheers
Older cars/trucks have relays under the hood and I have what I got the rig for. Yet being cheap, I grab easy fuses as there are so many different kinds that I pour them in a plastic tray on the bench for easy reach and most are color coded so I sight tells me which I wanted, and there is alway a few relays that go in my Dorman box and just lift lid and pick one needed. I can wire all my switches with sixteen gauge wire out to relay and depending on draw pick from relay to accessory. Keeps everything on short runs and so easy to put a few wires in a loom so it looks nice done. Good video for any newbie trying new to him projects.
I have been doing automotive wiring for years. I like your video. Two things I would ask about 1) Heat shrink if it is going under the hood would be better if you used marine type, it seals against moister. 2 Why not twist the wires together to make your connections even stronger.
@@red2965 , Hi Check Habor Freight heat shink kits. They have a version that is a marine type. When heated there is a glue or sealant that activates and seals out moisture. Since I have discovered it that is all I use.
Thanks big dog you know I normally don't do this hardly ever leave a comment At this time I was so impressed The way you explain everything and demonstrated The proper procedure Not only that The way you come across is very humbling no cockiness whatsoever I appreciate everything that you showed me today man God-bless and keep up the good work.
Needed to see this. I always use fuses but love what I just saw with relay. It's my new standard now. And I Love soldering my wiring systems.never fail.
A tip I'd like to share. On many of my corded tools, I use old vacuum cleaner cords, and direct wire them to the tools. Vacuums are always discarded, and I just pull up, cut the cord off, and go. Electric leaf blower, fans, heat guns, table saws, stereo equipment, portable lights, etc. Some cords are over 25 feet long, and heavy enough to use on many tools.
Well I sure learnt a hell of a lot from you, this video, here in ye olde England, many thanks to all the guys like you who can be arsed, Bravo dude. Subscribed.
I’m glad that you don’t need to use flux.. but you said you wanted to show us the proper way, which includes brushing on flux before soldering. Thanks for sharing.
Adam, the Owner of Your Passionate Groomer solder is rosin core. Flux is In it. I don’t like using the type you brush on. Guess I should have been more clear.
Added relays to my MGB for my headlights. The original way was to go straight to the switch, but the cheap quality switches that are available will fail in less than a year. So a hot lead from the battery circuit to the relay with an in line fuse. The current going through the switch is about 5% of what would go through the switch without the relay. Plus when the switch begins to wear the resistance will cause the headlight to dim. Relays are the answer to electrical issues.
Very Good instructional video.. i studied the hell out of switches and relays for a big off road project I'm doing. I've seen dozens of RU-vid videos on similar subjects and no kidding, I think this was the best. Simple concise and easy to understand. Two Thumbs Way Up! 👍 👍
pretty informative and useful vid. but one thing i will suggest is when you use the wire stripper turn it 90 degrees so the flat face is facing the way you are removing the plastic covering. doing this makes it easier to pull the waste waste, ie you dont have to pull so hard.
I am sure there is an invisible guy that lives in my shop. I can be working on something and I set a tool down and he makes it vanish. I don;t know where he puts it and then after a while ..... there it is.
My wife's Honda Civic kept having the headlights go off while driving at night. The car had been recalled for this back in 2011. Honda had routed all the headlight current through the headlight switch on the steering column. Over time this would cause heat damage to the switch. I added a relay, which now carries the headlight current and the switch only controls the relay.
Man, I appreciate this video. I'm just about to wire up my 53 chevy COE. This video should help with the relays. Solder size was a helpful bit of info too
First off, my electrical expertise doesn't go too much farther than installing car audio or the occasional light fixture/ceiling fan or outlet in a house. I've always used the crimp type connector for car stereos(or twist-on wire connector for household wiring) and all but one time, it has been successful. The power wire came loose on one of my cd player installs and since then, I triple checked that all of the crimp type connections were secure. That being said, I have never soldered anything until now. I used your method and soldered the wiring harness adapter to my cd player on my newly acquired Crown Vic police car, heat shrink tubing and all. It worked like a charm! I definitely won't ever use the crimp type connectors again unless there is no other option. Anyway, thanks for the excellent guide and once again, you gave me the confidence I needed to attempt it myself. Thanks man.
It basically is down to how much load is the switch rated for. Other factors are wire size, run length, cost, complexity and location of relay. Horns are good example for the need of a relay because of starting amps and inductive load but most lighting doesn’t need it if properly wired & fused. One thing to note. There are three types of DC relays standard coil, diode and capacitor. The latter two protect the switching mechanism be it mechanical or solid state from the BEMF voltages of a de energized coil. Only the diode type coil is polarity sensitive and marked +&-.
Thanks I used to be a Jimmy. Now I am buying a UTV and trying to learn how to do wiring with relay. Like your video and Subscribed. Keep up the no nonsense video. After this Video I am going to buy GOOD crimpers. Not a jimmy anymore.
It's always a good idea to clean the soldered joints with a little alcohol and a "acid brush", especially if you use flux. I recommend flux because it aids in cleaning the joint, and making a more solid bond. Good video!
Thank you. You are a good teacher. Good film editing with appropriate fast forward when appropriate. Your humble, knowledgeable approach is very appealing. Good Job.
the way to remember how to wire a 4 pin relay, is to use the compass method, pin 87 horizontal top pin, 85, 86, 30, are vertical, pin 87 north, N for New Accessory, pin 85 East E for Earth, pin 30 South S for solid 12v + and pin 86 West W for sWicth Wire
You have a good way to remember but you need to re-comment. You have your numbers mixed up and you need a few commas in there to make it more understandable. "85 86 87" should be "85 86 30"
I am a fan of the relay socket plugs. I've installed three 20 amp circuits on my van that are operated by 7.5 V relays. The relays work great to protect the circuit but when the circuit fails, it's always because of the relay. I can't find a quality relay that isn't made in China or Mexico that will last more than about two years. They say "a chain is only as strong as it's weakest link" and that weak link is always the relay. I now carry two spare relays in the vehicle at all times that can be easily swapped in the socket plugs.
Hello BBG, yeah good job talkin about fuses, many think its all about the voltage, can't get a shock from 12 v so they don't worry about things. What they fail to consider is that the car battery has way more amps than volts. Cool Kat likes auto electricity. Some wire insulation will flame, some just melt, either way not protecting the circuit is about the same as putting a penny in the old style home fuse box.Good job about using a relay.
Thanks for the video. I like how you show the "un-proper" way to do things and then show how theyre supposed to be done. The tool review was helpful as well.
Hey when it comes time to wire the head lights go to ebay and punch in relay head lights. You can get both relays the harness and the ceramic sockets for the head lights for around $12.00 makes it wicked easy .
Head light circuits on older mopar stuff had same problem. They ran power straight through the headlighy switch. Everyine one ive had ive wired relays in to stop melting switches. Also old Japanese motorcycleare notorious for these wiring issues
Glad that you made this video about soldering wires together on a car; other RU-vidrs have said that you should only use crimp or screw connectors because "solder is too brittle"...? Dunno why they say that; I never had trouble with properly-soldered joints' coming apart on rough roads.
