T1 Switched Power Source

[2019_Silverado_HC]

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 right fuse panel (passenger side) by fuse F27 which is a square shaped fuse, there is an additional prong next to it that will accept a spade connector which you can then run a wire to a separate fuse for whatever you are installing.  I hope this helps someone else since wiring diagrams are not readily available on the net yet.  Enjoy!

Good info, thanks.  I will be adding foot-well lighting  as well.  Hate getting in and not having it.  It is standard on my 2002.  Can't believe they got rid of it.

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

No issues on my truck.

I take it this power source works with the interior lights?  As when you open the door they come on and then go out?

If this connection has retained accessory power, are your lights always on? 

[2019_Silverado_HC]

RAP only stays on until the driver door is opened.

Yeah I figured that out after I wired it up lol. I was just concerned because my car charger stays on with the truck off and thought that was the "retained" accessory power

OK on my 2019 that connection is always hot.  Anyone have any more suggestions.  What is an easy way to test it to go off when the dome lights go off?  It's just me so no other help to turn on and off things while I probe with a test light.  I tried the one by the 50amp fuse and it was always on as well.

I hooked up to the one by the 50 amp and my lights will only come on once the truck is running, not with dome lights

Yep, problem is, mine are just LED's.  No controller so they stay on all the time while driving.  Not sure How I will like that at night.  Would rather have a switched source that is connected to the  dome lights.  I just need to find the wire to tap into.

That's what I did on my Tacoma. I had the foot lights and rock lights on with my done lights. If you find that wire, please let me know

I'm looking for the same thing (dome Light control) I am definitely missing footwell lights (as well as puddle lights.)

 

I don't believe it's something we're gonna find in the fuse box.  It's more than likely gonna be a bcm plug.  I think it was grey on the last gen trucks.  

 

Im not a fan of splicing into those wires so I'm thinking of making a pass through plug with a tap of the dome light wire.   

 

Same with my high beams to aux lights. 

 

I'll do some digging when I get a free weekend and let you know. 

 

Below is what I've found so far.

Anyone figure out if this is possible yet?  I know on the previous years you could tap into the BCM plug.  But wondering if anyone has done it on the 2019's yet?  I would love for the LED's to go on and off with the interior lights.
