Installing running board lights

I am looking for  some guidance. Bought some running board lights that I would like to turn on when I open the door to illuminate the running board step.

Anyone done this? Where can I run them up from the underside and what fuse panel and number should I connect them to?  Anything might help.

 

Thanks

Welcome to the forums...

 

Haven't done it, and you might get much better comments from someone that has, but the manual indicates that fuse 76 in the block under the hood is for "Electric Running Board". I would grab a multi-meter and see if that powers on and off according to the door being open or not - it might be what you need.

 

Otherwise, you might need to find the wires that power the overhead lights in the headliner to find one that's on/off based on the door being open/closed. If you can trace that back to its own fuse, you might be able to add a tap there. Otherwise, probably would need to tap the wire and use it to control a fused relay for the exterior lights.

I did this on my 2016 and I’m pretty sure the wiring is the same. I ran wires through the firewall and had them tapped into the some lights. That way anytime unlocked it or opened the door they would come on.

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

Cavity 1 on the black BCM connector in the driver side footwell is what you're looking for. It will do the lights only for sure. I did an install on a 23 Silverado LT using the below instructions.

 

 

You will need the wires also, seller is also a member here:

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?

      Feeling Vibration and Jiggles in 2024 HD Gasser Steering Wheel

      By Policeoff01 · Posted

      Curious, did anyone ever get a fix for the vibration reported here.   I have a 2024 Silverado with 6.6 duramax.   I’m noting the same vibration resonating up through the steering shaft into the steering wheel.    Best way to describe- like someone is tapping on the steering shaft/components and it’s resonating into the steering wheel.    thanks.

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.
