05 mustang gt started to put my aftermarket head unit in plugged everything up and it didn't work so I figured it was my adapter wiring but to make sure i put the stock radio back in and now it doesn't work so It could be my wiring I must have blow a fuse of some sort I checked the fuse box in the passenger side and only fuse #6 "Accessory delay feeds" was out i tried putting another in that and it still didn't work any ideas? #20 "Radio (Start)" was not burnt out

what I mean by doesn't work as in it doesn't light up no power

 

Did you check fuse no: 56 (20A) (radio) under hood fuse box.
