Have a quick question about the overhead console wiring. I was going to put in an aftermarket auto dimming mirror. I took the overhead console off and checked the wires. The +12v is hot all the time. Is there no 12v ignition wired. The other wires were ground, +5-6V and something that appeared like a low voltage data(CAN??)
Truck is an 08 Ram 1500.

 

Glad there are search engines and other forums that had the answer. Thanks for your help!
