[Ol Jawja Boy]

I had the radio pulled out of the dash. The harness which has the power wire(red) lost its charge. It has to be connected to the yellow wire for the speedometer and door locks to work. With the red wire lacking fire, the door locks will lock but not unlock. When I press the unlock button, the blinkers flash. Can some please tell me how to get fire back to the red wire. The radio, speedometer, nor unlock button will no longer work.
