2004 F150 radio will not turn on
My 2004 F150 radio will not turn on. This happened after I pulled the radio out to install an aux audio adapter. I put the radio back in and nothing. The radio will eject a CD and you can set the time but that is all it does in my truck. I pulled the radio and stuck it into another Ford and it worked fine so the radio is good. I have power on pin 1 of the radio wire harness but nothing on pins 2 or 15 which should have power when the truck is in the run position. Fuses 7 and 22 are not blown. The grounds on pins 4 and 13 are fine. I swapped the accessory delay relay with a known good relay and that didn't help. So I am kind of stuck.
Does anyone have a schematic of the radio circuits? Or has anyone dealt with this problem or have an idea what else I could try?
I see alot of people that cant get their radios to turn off but none who can't get it to turn on. I should say this is and XLT with the new body style.
