I installed my headers today and when i reconnected everything works fine but my radio. It doesnt even turn on. Its aftermarket. Any suggestions?

check the ACC 20 fuse, if its good, pull the radio, there a fuse on the back of that if those are good, check the wiring...

i had this problem after i pulled my motor the first time.. i just rewired my aftermarket radio myself, something was wrong in the factory wiring i guess. it would keep cutting off when i was driving. i ran a wire from the battery with an fuse to the radio power and grounded it in a good spot.. it turns on with the car and i havent had a problem since. i also ran all aftermarket wire to all the speakers from the amps so my radio now has nothing to do with the stock wireing
