I have a 95 Ford Ranger that I am trying to put a CD player in. I finally found the wire harness and connected all the wires. When I plugged everything into the truck everything works EXCEPT there is no sound. Im almost ready to give up! I know that Ford circled the problem for me but its only vehicle right now. Their are two wires not connected to anything off the truck they are blue and blue with black stripe. CAN ANY ONE HELP PLEASE IM DESPERATE FOR A RADIO AGAIN!
