Trouble with putting in new radio...
The buttons broke on my old radio, so I go and get a new radio, match all the colors and connect them and viola, no power. I'm looking for a wiring diagram specifically for a 94 f150 with the factory amp but cans find any consistency. From what I can tell the light green/purple wire leading to the connector is what should have power, and it doesn't. The test light only lights up on the yellow/black wire and the orange/black wire. Then it lights up as we'll on the wires on the opposite sides of the connector. Please help I don't know what to do now!!
