Ok good subject here. I spent 2 months trying to figure this out and as of yet I've got nothing. So if you wire to the dome you PL come on any time your dome is on. I like the (only when the truck is off idea. That could work but then again when I'm out in the coutry with my lady I dont want my PL to come on when I turn the dome on to find her bra so that wont work.
I wanted to bypass the dome light and go straight to the source. The keyless entry box(s) but here lies the new problem when you lock/unlock it sends power to the dome and door lock actuators. I thought that would work perfect but the door lock switch on the door sends power right back to the box(s). So that is most of what I have learned. Any more questions feel free to pick my brain.
There maybe something I haven't thought of that I tried.
I Would love to find a good answer to this problem. I want it I need it
