Sorry.... I just realized you posted that before. Been a long week!
 
I not sure where to look for the BCM connector, can you help me out?
White connector under your dash. Driver's side.

It's where the green wire is going into.

1 row of pins. 3 Over. It's one of the two gray wires in this connector.

I installed some RGB footwell lights this weekend (picture forthcoming) and part of the project involved locating a switched power source and preferably one with retained accessory power.  In the righ

Yes There is only one slot that is switched. It's the spade to the left of the 50 amp circuit breaker. Top right of this picture. You have to use a spade connection to grab it and split it off

Hooked mine up last night. Wired them into the dome lights. Thanks Smoothbassman!

 Has anyone had the issue of this power source cutting off and back on when the truck cranks from auto stop start ??????

I am, I was wondering why my dash cam was cutting on and off, it doesn't happen every time though.

Hoping you might be able to help.  
 

I have the same Opt 7 kit as you.  I have a spade powering it and connected to the open prong next to the 50.  That works fine.


I ran the aux wire from the Opt7 control box to the grey wire in the BCM and T tapped into it as I want the lights to power on and off with dome.  
 

I have everything connected and grounded properly, but can’t get the dome feature to power on and off with this kit. 
 

what am I missing?  Do I need a different power source since this one is switched.  Super frustrated.

You mentioned  adding relays for your footwell leds. Is it really necessary with such low current draw? 

I still can’t get them to come on and off with the door.  I’ve tried everything.   I have to manually switch them off as they come on every time when I open the door.

I just bought the Opt7 kit. Did you ever figure out how to get it on/off with the domes? I definitely want it coming on when I open the doors but don’t want them on all the time while driving

I still can’t figured it out.  Mine stay on and I use the remote to turn off.

I'm lost. I have the Opt7 kit fully wired in. Connected the accessory wire to the grey wire (dome light) on the driver side. I tried every spade connector on the passenger fuse box. There's one that's RAP and a few others that are always hot. I want the lights to come on when I open the door or the dome light comes on. With the RAP power, it only comes on if the vehicle is on. With the always hot connections, the lights stay on constantly. There has to be a spot in the fuse box that's door/dome activated... I love the lights but I need a way for them to come on with the dome/door without running all of the power off of that 24 gauge grey wire on the plug...

Yes i have as well, only with my Roof mounted dvd player i installed. my radar detector doesnt shut of thou, so its probably just a drop in voltage causeing the shut off. not a full discharge of power. I just got the Autostop Eliminator and will hope this will just cut the problem out all together as i dont want that feature anyways. save on gas milage my ...

Thank you for taking the time to post your suggestion.  My 2015 Silverado did not have the panel on the passenger side  so I was unaware it even existed. My dash cam now works as it should.

Hey guys not sure if your still trying to figure this out but I have the same kit as you. If you want he lights only to come on with dome lights you just connect the power wire to the pin for the domes on the bcm. If you want it to come on when you enter and exit but also want it on while your driving you run the power wire through the grommet to the engine bay and wire it to the purple wire on your headlight harness. That is the parking lights wire. Then run the accessory wire to the dome light wire in the bcm. This is the way I have mine set up. It took me a while to figure it out. For some reason when you try hooking your power wire to the bcm headlight wire it doesn’t do anything. So if anyone is still looking to do this and want it to work this way. This is the way to do it. No relays needed as this kit has a control box. If anyone needs help just message me.

I haven’t messed with mine since the original install, but I really want mine to come on during door open/close and while driving. That setup sounds like exactly what I want. Do you have pictures of where on the BCM it connects? I’m sure I can find the purple headlight wire but I’ve had a hell of a time finding the dome wire, especially since online diagrams are sparse. It would be awesome if you did a short writeup based on the wires you tapped. Thank you for the update, you’ve re-piqued my interest!

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.

      when it's greyed out that is it's way of telling you that it's downloading the patch in the background. Eventually it will be fully downloaded and then it will prompt you at ignition shut down to run the update. I highly recommend doing the update once you get home and can run it a few times. I've had several issues with updates not going the first time around and I had to retry the update multiple times in my driveway before it was successful.   Some updates are huge and take awhile to download. You can help it by connecting to your home WiFi and keep the truck on service mode for the ignition and keep it alive for awhile on a battery charger too. There are specs it needs to be in for updating such as a full enough battery charge, no running ignition, etc.

      I am not techy at all but wondered if you have the truck running but sitting still in park as some functions gray out as soon as the truck is moving. I believe in the settings for updates you can choose for it NOT to update and I wonder by chance if maybe that was chosen before and now it won't allow you to chose to press update, I think that is back in the settings menu where it has all the items one wants on or off etc. Also I assume you have a wifi connection and checked that it has some signal strength, not that it would have anything to do with the grayed out updates choice in that case. What I am thinking out loud of here may be be of no value but thought I would suggest it, sometimes it can be the simplest thing that resolves an issue.
