I'm trying to hook up an aftermarket TV in my truck. I've got the wiring harness all wired up, how ever there are two power (constant 12v yellow lines) and two grounds on the harness. Once I install this setup the radio only will power on or off with the power button, reguardless if the key is in the ignition or not.
I'm wondering how you have to hook this TV or anyother aftermarket radio up to turn on and off automaticly with the key in the ignition?
