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?

      Gas Prices

      By richard wysong · Posted

      Question for you Grumpy, why is diesel so much more than gasoline? Seems to me that it may be slightly a little less refined than gas and it doesn't have 10% alcohol which presumably lowers the price of gas

      Transmission Temperature Hitting 220s

      Thanks, so being a different beast altogether, anyone know what the "optimal" temp is for the 10L80/90 for proper shifting?

      How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.

      Gas Prices

      By Grumpy Bear · Posted

      Out and about yesterday on a long Saturday drive I passed a lot of Shell stations. My preferred, so I pay attention. Lot's of small town Illinois so not six stations in three blocks like the city.    Everyone of them over a radius of say 100 miles had regular at $4.19 but one which was the one closest to home at $4.15. However Premium pricing varied greatly between 85 cents over regular to $1.50 over. I'm not counting the price of the station with the lowest regular so the reference is the same for the remainder and all within the same brand. However the spread discrepancy holds across all brands.     @txab, any thoughts on that?

      What are your thoughts? The Chevy Blazer relaunch was an epic case of 'lunchbag letdown'. Jeep Wranglers and Ford Broncos stick out like a sore thumb.    The AI photos do not look like a 'retro version', but shrunken Tahoes. Get away from the 'futuristic look'. I've seen two concepts. One had rectangular headlight like a Rivian and the other way too big headlights (similar to a previous non-Wrangler SUV) should include dual round headlights like the early version.   If not this would look OK   At least it has GM styling (albeit the K2XX) A lot of the images floating around look like Bronco IIs or the current Bronco. Looking at the Broncos in my area (central Ontario, it seems to be a mix of 2 doors and 4 doors, 'mall rated' to ones that could go offroad.    I'm sure a AT4 and AT4X RPOs could be outfitted similar to a Rubicon if the braintrust understood the whole offroad scene. Crossing my fingers that if it does see the light that the front air dam/bumper doesn't extend below the center line of the tire...
