Hey where did you push your running board light wires through? I’m having the hardest time finding the grommets being the wheel well shielding stuff

awesome, and i can actually t-tap off of this for the left running board light. Thank you so much!

So confused, X1 know when it's door open, left turn signal, right turn signal and 'running head lights'?

i have 4 wires per running board light, do i not need one for each wire?

Thanks for the updated link, just curious is that $5 per cable so $40 for the job I need to do, or is it $5 for what i see in the picture lol (one is a lot easier to explain to the wife)

Wooo awesome thank you! Matt I was pretty sure that was the correct answer I just wanted to make sure. So it appears I have to tie into 4 pins for parking, curtesy (white door open) and left/right turn signal. I have to double check the names of the turn signals now to make sure I’m not trying into the switch but into the “light” because I’d like them to flash with hazards too.

Using the knowledge you guys have unlocked for footwell/kick plates and assuming the x1 pin1 will work for 'white' assist lighting for runnign board lights, my question is as follows: According to upfitters electric body building document for the 2023 silverado: X1 pin1 shows 'not occupied' and you guys say it works for the interior lighting switch X2 pins 1-4 show the same thing, but the right/left turn signals are on pin 23 and 29 on x2, think i can wire the interior light on x2 also? (i don't own a multimeter, should probably go buy one lol) Also do you think the pin labled "Headlamp switch park lamp signal" is what my led manufacturer means by "+12V Parking lights"? Their installation instructions leave a lot to be desired, 4 wires and all they say are: White - +12V Door assist Red - +12V Parking LIghts Yellow - +12V Turn signal Black - Ground Thank you in advance!

THANK YOU! This is the answer I've needed for the White door open light on my 2023 LT, now if i could just remember which wires for parking and turn signal in the BCM (I have it written down somewhere lol) EDIT: Question: X1 pin1 shows 'not occupied' and works for the interior lights X2 pins 1-4 show the same thing, but the right/left turn signals are on pin 23 and 29 on x2, think i can wire the interior light on x2 also?

If it’s a 2022 refresh or newer, the dome light is on a logic circuit and it isn’t as easy as “open or closed”. I have lights I want to install on my 2023 and have been trying to find the answer for months lol

I have search back a few months and see lots of threads about footboard/interior lighting and those are helpful for finding the dome light (unless you have a 2022+ or 2023 Silverado/Seirra like me lol). My concern is finding the other wires required to connect these. I'm not clueless on how to connect the wires, just want to be more cautious on doing it on my brand new truck, and make sure I have the right wires. According to their diagrams they need: 12v+ Door assist - I assume this turns on the white light when doors open 12v+ Parking Lights - no idea what these would do? 12v+ Turn signal - flashes with turn signal Ground My main question is are all of these available in the A pillar? if so, anyone happen to know which wires or have a diagram/picture? Lots of great information here. Have enjoyed reading other threads! Thank you so much in advance
