I purchased an Opt7 Footwell Light kit that I'm going to install in the 2019 Silverado. I have been following a few threads on how to install the lights, and have gotten the basic install down for me to be able to control them remotely, however, I cannot figure out the door light feature. Does anyone know where I can find the hot wire that activates when the door is open, or conversely when the dome light some on? I need to tap into one of those two wires to get the light kit to operate when I open the door, but I absolutely cannot figure out which wire is the correct one. Anyone done footwell lights yet, or know where I might be able to figure out where to find that wire? How would I even go about manually testing for the door/dome activated wire..? Thanks for the help.

If one image on another forum is correct it should be the 3rd wire in on the white plug under the driver side dash (the plug closest to the driver seat). However, I want to confirm before I tap, as I hate tapping these wires and there are multiple grey wires in that plug...

It's the 3rd gray wire on the white BCM connector.

See the photo where the green wire is going into. e3cc59e296806fd70345971444793a4a.jpg

Awesome, thank you sir! That's what I thought, just wanted to confirm with someone who's already done it.

Another question, where the hell did you mount your LED strips under the dash? I just realized there's not a nice flat place to mount them like there was on my 2012 Tahoe. Just a very crooked metal bar. Interested to see where you put them

Alex, 
 
I am also curious to where to mount the strips?
Guys

Here's how I mounted mine.

Zip ties on drivers side and rear seats. You won't be able to see any of this from the outside as it's under the dash.

And on the passenger side theres a nice spot where you can stick the adhesive to

Just get creative and mess around until you get something you like.

Hello, if I want my footwell lights to come on like my gauge lights, where what power would I tap into?  I would like my footwell lights to dim like my cluster lights.  Thanks in advance.

Hello, I guess the 2021 GMC Sierra changed up things a bit.  I do not have the grey wire coming out of the white plug., Have anyone put the foot well lights on the 2021 truck, if so what wire did you use and the location.  Strange thing is when I disconnect the plug the lights goes out on the dome, but I cannot find the individual wire that controls the light. Help!

The bottom picture is showing brown, pink and gray. You need to use the white connector to the left or towards the seat.

I've read through all the threads I could find on this and it seems most folks are using this method to power them. However I have the opposite question that doesn't seem to be stated on any of them. Do they power down when the dome lights turn off? Plan on doing this in the next few months when it warms up and trying to plan out this mod and others.

    • So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.
    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
