I have a 02 I just bought the previous owner had taken the factory radio out and put another one in. Before I got the car he took his stereo and put the factory one in the slot but didnt wire anything. The factory harness comi g from the car has been cut but the wires arent spliced or tampered with I tried to connect the factory unit bye color but it didnt work. Also after messing with the wiring for the radio my dash does not come on (speedo rpm oil pressure etc) until I switch the headlight **** but my headlights stay on when I turn the key into the on position regardless of the ****. Any help at all would be greatly appreciated
