Radio Wiring (RAP and Lights)

[rgosart]

I am sure the answer for this is posted somewhere, but I was not having much luck finding it.

I installed a new radio and everything works, but I would like to find a way to tap into RAP for my switched power source and a wire for the dash lights so that the radio will auto dim when the lights come on. Where should I look for wires for these functions?

Also, where did everyone mount their usb inputs? I have an LS truck so it does not have the full console. I have the center seat console.

Down behind the pedals. Something like this. This is from @Galante. It's on here somewhere...

Doesn't the factory radio stay on with RAP as well as dim with the headlights? Aren't these features retained with an interface like the GMOS-LAN or PAC?

Yes the factory radio does and you're probably right about the GMOS-LAN or PAC adapters. I only used a steering wheel control adapter. Didnt care about chimes or onstar

your deck should have a lead for illumination (dimming), the power wire you are currently using would need to be changed to one that supply's rap power, the adapter you decided to not use would have those options already configured.

Ah. Yeah, so you're gonna have to tap the circuit Nate posted for the RAP. For the dimmer, you can just tap a dome or dash light circuit, maybe one coming off the headlight switch.

I understand. I was asking for the locations of wires I could use for those functions and @HiHoeSilver answered that

you might try googling for the upfitters guide it will have all the wires diagrammed, will make things easier.
