How to wire your LS Swap, for free, no money, none, zero 

I bet them neighbors hate you😂

Don’t worry about the length of the videos! If other people are interested in doing a LS swap like I am, the harness is the most intimidating part and it’s super valuable content to have someone literally go step by step through it, to show it’s not THAT complicated. I’m interested in swapping into an E30 and I feel like the harness part of the swap gets breezed over in most write ups.

A lot of this is "familurizing" ones self as to the lay of the land so to speak. Each sensor, its name, its location etc. slowly eliminating the apprehension of all the wiring. Knowledge eliminates all fear. Thanks JR, a novice cant see enough of this, rinse, repeat.

There's nothing like visual tutorials. Thanks, JR! I can't imagine what hiring a mechanic to do this work would cost.

I have worked as heavy equipment mechanic for many years as it was easy to go to some logging camp and go to work fixing on anything from the crew buses to machines that pull logs out of the woods. Out in this situation most equipment is old and I fit right in but now this stuff here that you just worked on is ten to twenty five years and that old again. In other words, If I was still able to work as I got crippled up fifteen years ago and youtube and a bed is my life. I can use crutches now but who hires a guy who can't carry his own tools. I am also 72 years of age... I built hot rods and fast cars and trucks, rode my harley till just a few years ago but using a crutch to hold the bike up was just getting too hard. I had a trike as well but I couldn't carry my tools ... I was a big strong guy who did just about anything I wanted to and then life turns a one eighty on me. Guy fell from his roof and would die so I reach out and caught the three hundred pound fellow and it tore his tee shirt pocket. I woke up in a hospital with a broken neck, and lumbar was "fubar" or from L2 through L5 were broken and more than just once. Doctors know a good thing and operate on me several times before they find the one link that would of fixed me but because of all the surgeries, no can do. NOW... as a mechanic if you break something of someones rig, you fix it if you are a decent person but doctors go ...oops. I turned on closed captions so I could poss the video and read it and start to understand this stuff and it makes perfect sense. I loved working and working on old trucks or cars were my jam. I just never got to this part and when I look under the hood, it looks too scary to proceed any further... that is till now. Its actually easier than say older stuff that your trying to get rolling. No plugged up carb cause it sat too long or other .... thank you for making it so damn simple. I have tons to say but your not going to read someone whine about his dicked up life.

Damn. J.R just attacks the motor with the spaghetti monster all tangled and twisted and let's us watch him battle it while narrating. Bravo

This is really helpful. I have been anti LS because I thought it was too complicated. Now I see it's kind of simple. Thanks !

Son of a B. I didn't realize it was this easy. A simple wiring diagram and your video makes it possible to do this in just about anything. FML now I'm gonna be sitting here thinking how to swap out my riding lawn mower. Seriously. You make it that straight forward. THANKS for the kick in the brain to think for myself a little. 👍👍👍

Technically you wired that LS with 1 hand, I like the longer videos also.

This is the road I went down with my VW Vanagon Subaru swap. It took some time to weed out the unnecessary wires, but it was virtually free and I didn’t have to pay some guru in Canada to do it.

After I spent so much time tearing my harnes apart then doing all the stuff the intnernet said. It’s was like only removing 3 wires from the harnes. It could have been left alone. All the computer stuff could be dealt with. And any extra wires can just stay there. Honestly the factory loom is better than my jank tape job

We just want to be on RU-vid and have your attention Instead of being good. Enjoy your weekend! Thanks again for your time and your work. Time from family is a good thing you giving up some to make these videos, priceless! Thanks

I love these type of videos.. right to the point.. no bs.. thanks alot!!💯💪🏾🌍🙏🏾

Thanks JR as usual straight to the point and clear and understandable

I love the long videos. It gives me something to watch while I’m farming

I did not watch the whole video. But believe I saved it for this winter when Im going to be doing this. Thank you JR. You channel really gave me the drive to do my driveway engineering.

You do good work sir. Keep it up, you will succeed with all you future ambitions 🇺🇸 Thank you for all the great insights on these projects!

Thanks for the informative video. Wishing you luck in your new business endeavors.

I found this enjoyable to watch while setting up my fishing gear for a trip, I find stuff like this ever so more enjoyable than watching TV these days.

Thank you for the info and content. You keep showing how easy it is to swap a LS. I don't mind long videos at all. I prefer them as you can explain in better detail. But with the world and its instant gratification everyone is in a big dam hurry. Thanx again brother.

Thank you, im studying up and aquiring parts for my swap, i'll definitely come back to this

Like a boss! Love your attitude... simple common sense and to the point. Yes its clear and i'm buzzed 🤣! God bless brother

Very impressive, this upload... I will be tackling my Gen4 soon!

Love this guy he’s a straight forward dude

Will watch later. Thanks for your no BS info!

Thanks for the video. It is very helpful. I have a complete 03 donor as in the whole vehicle. I’m doing a complete engine & transmission swap.

Liked, subscribed, bells on and I'll be watching this video atleast 20 times once my 5.3ls is ring gapped, canned and ls6 springs and other head crap is finished. Great video and this definitely cleared up a lot of confusion from other videos.

I watch the video from start to finish and I have learned something Everytime.

Thanks for the video's! I would assume us newbie's appreciate the longer videos. I greatly appreciate your time.

Patience=virtue. Good vid!

Thanks brother your the LS TOUR GUIDE. LOVE IT.

I'm doing a 6.0 swap in my e36 bmw and luckily I'm pulling the engine from a friend's Yukon.. im going to pull the engine, harness and computer but im going manual so im happy I came across this video because it does show how simple it is to wire up. Thanks

Watched the entire video, thanks for detailed instruction video , keep up the great work made it easy and a game changer when it comes down to saving money for other parts for my project..

Thank for making this long epic vid bro I watched the whole thing

Going to pick up a 03 Silverado 4x4 rust bucket that runs for 700$! Your video is setting me up for future project for Cheap!

Ill be watching this many times. Thank you

Thank you for taking the time. 👍

Great video JR. Thank you.

Appreciate yet another great video

You make that look easy! I'll have to try it. Now to find a donor and a project.

I made myself all my 6L / 4L80E swap it cost me zero and everything works wonderfully in my 1986 C10

Once you know where the harness lays on the engine (which the attachment brackets show you) it is literally Plug-n-Play. You may have to hunt for the sensor to plug into, but it is somewhere in the area the wire is dangling. Great video!

Subb'ed (some time ago) and watched this whole thing- now it's saved in my LS Project folder as I prep to LS my Land Rover Discovery II... This is really great info- so simple really- I love how you laid everything out- it is nice that all the plug shapes are pretty different- really does make it make a ton of sense and logical. Now I have to wait for a Silverado at my UPULLANDPAY that hasn't already been shredded through.

did this on my 1994 k1500 LB7 duramax swap! really only needed 3 or 4 key ons and a couple grounds from the ecm! subscribed, sir. thanks for the info.

Thank you bro you the greatest 💯👍🏻

Really appreciate the information great video

Really appreciate your videos and you sharing your knowledge, it’s help me out 10 fold

Thank you for the tutorial, I am actually looking forward to swapping out a tired 260k mile 4.3 in favor of something much better. This was really my only apprehension, and yes I could have figured it out in a few hours, but I like to watch how it’s done first. Thank you brother.

Good info! Going to come in clutch on my 74 Nova swap. Thanks!

👍🏾 Definitely was a big help

Appreciate all the great info sir, in the process of doing my 1st ls swap and very budget minded. Been to the junk yard several times as I did not get harness with the 5.3 but its getting sorted out slowly but surely, thank you so very much for sharing your knowledge sir. May God bless you greatly.

very informative and straight to the point.

Yeh, this was nice. Thank you!

I watched it straight through because you intimidated me hahaha. And you're right I'll be watching it again. Perfect timing for this video I'm installing a 5 3 in the back of my Baja Bug to swap out that Eco turd. Thanks man

Great vid. Very thorough, real world info. Keep up the good work 👍.

I love the long videos.

Great job JR, thanks!

As an aside, I do like what you've done with the pneumatic casters on that engine hoist. What a great idea. I have some of those under a 55gal barrel rig and it has blown out the tubes and tires because of the weight and UV and I've gone back and got the solid rubber wheels and haven't looked back. Also, I pulled a 4L80E today based on your past videos and I appreciate the low buck commentary. Mine is going behind a 5.3 in a 92 Merc R129.

Saving this video thanks jr

Watched entire video. Still looks intense but took the edge off 👍

Just doing my part for the algorithm. Thanks for the information!

Thanks, this is a tremendous help

Great video- thanks for caring about us noobs.

Thank you sir I appreciate your videos so much you're a genius

thank you mr. engineer. Very informative as well as entertaining. Ibelieve my dogs outweigh yours by an oz or two.JUST adding failed Texas humot.I FEEL much more confident wiring ls1 into 02 Z28 .SORRY to cheat algorythm as i paused and rewound and took notes,snapshots,and sketches.took me over van hour.time well spent sir.Great job explaining showing in laymans terms,you sir earned your coffdee,thanks again

Awesome dude I'm about to acquire a last pullout complete car running for a possible rear engine apocalypse buggy...cheers

Dude where were you when I was dragging my engine hoist through dirt in my back yard 😂😂😂 that engine hoist setup 💪🏾 with the caster’s on it is pure genius

Great video, thanks!

Yes you just helped me decide to go ls

Ok thanks. I Never done this so yes I will watch another time when I am doing it.

Great video! I did a similar install from a 2001 to my 55 Chevy truck. I used the entire harness - still working on it, but it can be done! For me the biggest issue was getting the entire harness off the donor and mounting the body computer and interior fuse block/patch panels. I had to so things like patched the turn signal wires to my new column, stop light switch, etc. What made it work for me was having access to the donor trucks wiring schematic. Still in progress but going great, especially with the Dakota Digital instrument cluster which uses the PCM for most of the gauges. Oh, it cranked right up with no changes to the PCM. Amazing !

Your the man JR.

Great video. Wish I had hooked that loop on the main loom up first. lol

Wow love you man so clear and great tutorial thanks

Man! Thanks jr! big help

Great video!

Great video! Thank you very much.

I thank you very much for sharing your experience with us ya made it easy to understand and workable ya Don,t have to be a rocket scientist to do this with what ya done is all l need to do mine bought extra truck for the harness wrong got all l need by your way mine is going in 1949 dodge 3 ton water truck 6.o litre same shit different pile to haul our water for our house took out hole motor and tranny so lve got this thanks again for your help l,m on board signed up for more to come so from Canada 🇨🇦 SK later 😊l just found ya hopefully ya still around keep up the great work

Awesome thanks for the info

I found this very interesting. I couldn't understand why people keep buying all the expensive stuff.

Thanks JR.

Thanks for breaking it down!

thanks getting ready to swap in my 84 monte ss

Dude I know this is a couple years old. But thanks to video saved my ass.

Thanks JR!

Good shit bro🤙🏽

The stock harness and fuse box works fine,my only issues were the random odd codes that would hinder it from starting.I would get it running let it sit a week or so and bam code po452 evap sensor and code po 107 absolute manifold pressure.I will get it figured out,minor issues !

Best video ever

Great video & thank you for sharing, this info will be very helpful when I do my 5.3/700R4 swap into my 69 C10.

good info.thanks

Hey. hope your doing good thanks for the vid.

honestly there is already a lot of resource about the LS. I would really enjoy a talk about the the rest e.g. transmission/diff etc upgrade.

Plug and play... I like it!!!.

I just watched this video again a year later. Thank you

The reason people get a holly is they don’t have to mess with the immobilizer, it’s not just for the harness. The holly also comes with a tuner, nitrous/turbo controls, a little screen, and a wideband.

Great informative vedio

Your right ! its just wires and connectors . Don't overthink it and save some money. It makes perfect sense 😊.Question. can i use this harness in a 6 speed 94 lt1 firebird formula? Planning to Ls swap in the future.

Nice job

Very good. Where does that steel hook looking thing connect? Very good

Helpful video, thank you for it. Just letting you know you have some albino koalas in your yard
