Fog Lights stay on with High Beam (All Lights Mod) Chevy GMC CHEAPEST MOD on the market 

just did this on my 2015 GMC Sierra and it worked like a charm! Very easy instructions to follow and very informative! Thank you

About to install mine...appreciate your reply on tiktok few weeks back glad you did a video!!!

Exactly the video I was looking for!! Thank you so much for taking the time to make it bro 😎 🔥💯

Worked like a charm! I ordered the diodes, installed as shown, and I can see clearly now with fog+low+high beams all shining at once in my 2017 Chevy Silverado HD!!! Thank you for the hack… it always drove me crazy that the fogs went off when I flicked high beams on!

Man I appreciate you sharing this will help me a lot keep it coming please

Thanks for the help. I been wanted to do this. I just ordered my diode.

I have the same problem with my Dodge Ram thanks for the info keep up the great work

Just installed my diode tonight. Thanks for the guidance.

I like this guys style

That is so awesome!

Thank you! Well done!!

Nice thankz for da tip

PERFECT !

Hi there love your video’s I have a 2015 gmc Arcadia I’ve found the brown connection block but it’s wired up differently would you know the procedure

Very informative...how do I get this to work for 2018 honda accord ?

Can you do this to interlock third brake light with reverse lights?

Do you have the info or wiring diagram for 2022+ refresh and 2023 Silverado? The plug colors are different I think. I was about to buy the boost auto version but I new it was super simple I just need a little more info to complete these upgrades.

Long shot but by any chance would you know how to get the tow mirror lights to work as marker lights and turn signals? I got a 2015 Silverado LT I added sequential led tow mirrors and hooked up my turn signal just fine but can’t figure out how to get the light to work as marker light

Can you do a video on replacing the 2 front middle parking sensors on 2021 Chevy 2500HD Thank you

So I'm completely ignorant to electrical stuff but am wondering if this could short out the computer system and cause me to void out my warranty? Also, does these step's work for a 2016 Yukon Denali XL?

Additionally, the 2023 fog lights are integrated. No bulbs to change and haven’t been able to locate any type upgrade fitment for them. Any info on this would be greatly appreciated.

the magic question is, where do you get the pinout diagram to figure out where to plug in the diode? I have a 2001 GMC Sierra

This may have been covered. The silver side (wire) of the diode is called the cathode and on a schematic it is represented by a vertical line connected to its wire. The other wire is called the anode and is represented on a schematic as an arrow pointing towards the vertical line. DC Current DC always flows opposite the arrow, or from the Cathode to the Anode. What we are doing here is taking the controlling voltage/signal from the HighBeams (pin 18) and letting it lend its signal to the Fog control circuit (pin 10). Since the signal/current can only flow against/opposite the arrow the high beam signal gets to the fog light signal but not the opposite way to not let the signal from the fog lights to get back to the high beams. as it's isolated because of the "one way only" diode. To answer "will any diode work?" Any diode with a PIV (Peak Inverse Voltage) of greater than 12volts Direct Current (your vehicle is 12 volts) and a typical minimum of a half amp, you should be covered. The most common general purpose diodes that you will see are 1N4000 (50V@1amp) through 1N4004 (400V@1amp). Anything over 20 volts (example) is overkill and just fine. I hope this helps. This same scheme is used by boost/burst/whoever to allow the low beams to turn on your fog lamps automatically with your low beams. The difference is that your diode costs a few cents and a similar diode in a heat shrink sleeve with crimp connectors costs $24.95 + shipping at that auto supply site. WINK WINK Get it? (You will need to find the pin for the low beams, connect the "cathode (band)" of the diode to it and the anode to the Fog Light pin). This way the low beam signal lends its voltage to the fog light circuit.

yes sir, websites sell the same diode for 20-40$ each to put on heat shrink and t taps.

Is there a specific diode I need or what. Thank you

the diodes come in different "amps and volts", what do I need for the 2022 3500HD

Will it hurt anything if it's install backward by accident. I plan on doing the fog light and cargo light mod but don't know the direction of the cargo.

will also work on 2007-14?

WHERE did you fiond wiring schematics for your GM truck?

Thats awesome brother thanks for sharing. I just installed an Amp step on my Silverado, I noticed that you also had an Edge. How do you install 2 plugs on 1 OBD port?

Does that work for any chevy model

I have a gen1 colorado idk what the hell were they thinking making the truck unable to turn on low and high beams at the same time by default

I fixed my drl bit now my fog lights don’t work, could this make them both be on the same time?

Only thing is that even if your fog lights are not on or if you don’t want them on this makes the fog lights come on with the high beams.

I did the same thing on my 97 GMC K1500 as I used it so the brights and the low beams stay on at the same time as I just did it at the harness at the switch and ran it like a jumper without cutting or removing anything.

Where to buy diode or any specs I need to know when purchasing diode ? Thanks fir the video !!!

Will this work in 2014 chevy traverse??

Will it work for a 2007 sierra nnbs

hello I really liked your work, I plan to do it in my car, it is a 2004 trailblazer, I have a question, please help me, I am a little afraid that when it is used for many hours the high beams can get quite hot and melt everything, for which is plastic, is it possible or not?

will it work on a trailblazer v-6 4.2

GMC 2013 wanting to turn on low beams high beams and fogs what’s up?

Hey does that work only to have the low beam and fog lights on. Or to have markers lights with fog lights itself. I have a 2013 yukon but when I turn low beam, I have to turn on fog lights manually and thats no good.

Not sure if this was says already, but I ran the silver end to 22 instead of 18. This showed my fogs to turn on automatically with my lows, AND the fogs STAY on when I turn the highs on!

Hello. I have a 2019 gmc Denali. I have followed your video. But won’t work for me. Why?

Will this mod work for 2009 escalade?

Would it work on 07 suburban?

Why not use the fuse block under the hood and slid the fuse out and I sent the diode and slide the fuse back in? I did it this way to mine and didn't have issues.

Will it work for my 2022 Ram 1500 ???

Good info but confusing. Not sure why no one is talking about it? You demonstration does not match the wiring pin out shown? If you look at 6:35 you inserted the diode in pin 18 and then pin 7 (blk/purple) So my question is what is correct? The drawing your showing (pin 18 &10) or your video (pin 18 & 7)?

What size diode 15 amps?

Is there a way to do the rear cargo light? I hate that I can’t turn it on while I’m driving.

How can I make the LED Daytime Running Lights stay bright while the headlights are on? I have a 2016 Silverado and the DRLs are pretty bright, but when I turn on the headlights, they dim to about 50%. I want them to stay bright at night.

How to do this on ram 2018 2500

This will work on my 08 ? Any help plx

I didn't see a link to find the diode on amazon, maybe I'm just missing it but can you add that to the comments?

action starts 4:17

Will this work on a 2011?

Can you do it with just a wire jumper or do you have to use a diode

What size do I have 15 amp?

Same brown plug and same holes for a 2009?

Will this allow fogs to be turned off with high beams on? 2017 Silverado.

just curious, what if it was in reverse? will it ruin or short the bcm?

you plugged the black side into the wrong wire

Looks like it would be unsafe

u can 9nly do this with a Denali model only

Check your state laws. It may be illegal to have your low and high beams and fog lights on at the same time.

It’s easier to do this in the fuse box

People sell this for $20 online! HAHAHAHAHA

This setup screwed up my high beams operation 4 months after installing. Total junk.

WAY TOO MUCH TALKING AT THE BEGINNING OF THE VIDEO. in fact I didn't even finish watching the video because there was so much talking and not any doing like talk while you're doing the video of what to do.
