I’m assuming these are the same for a custom. I had the fog lights put in by the dealer and for some reason I can’t get the diode to insert into pin #10 (the wire they installed with the fog light setup seems slightly thicker than the rest). This is the second night in a row I’ve spent around an hour trying to get this done... Any tips out there to help me out?

Hey get the boost auto parts mod. They have a couple different ones. They work with wire taps. 
here’s a link for the auto fog lights mod.

This diode installation allows all of the lights to remain on simultaneously when the high beams are activated on GM vehicles. The diode is super easy to install, you need $2 and 10 minutes. 9 of those minutes will be spent congratulating yourself.After diode placement your lights will function as follows:

• In auto mode- whenever your lights come on automatically the fogs will be on also.
• Low Beams & Fogs- Only Low Beams & Fogs will be on
• High Beams- Low Beams, Fog Lights, & High Beams will all be on (normally by default)  The vehicle turns off the fogs when in high beam mode, but this diode solves that.
• MAKE SURE THE SIDE OF THE DIODE WITHOUT THE STRIPE IS IN THE 10 PIN. The diode allows electricity to travel in only one direction. 

With this are the fogs suppose to come on with the daytime running lights

They are tied to the parking lights so no. I will post more info below.

EXSlider400,

 

Thank you very much for the information. I appreciate your willingness to share your knowledge. I didn't know I wanted to do these mods until I read your post! I was hoping you could answer a few questions for me?

2020 Sierra 1500 SLT

Foglights to DRL - could you share the plug/pin numbers and which way the diode goes?

Cargo lights w reverse - same. Plug/Pin numbers/diode direction please?

I've got the 1N4001 diodes in my Amazon cart. Those are the correct ones needed to accomplish these mods, right?

 

Thanks again for your help!

No figure out how I can keep my task lights on in drive.

Thank you for sharing this. Can’t wait to do this mod

I like the cargo lights with backup mod. That would put the hitch light on and help the camera view.

I did put LEDs in the backup lights. It mode a huge difference.

Personally, when I get my truck and do this, I'll be de-pin the wires and actually crimping this diode in rather than just shoving it in.

This was pretty easy to do and works perfectly!
