  • Pay attention to the dash light/dimmer wires. If your radio dimmer wire does not match the vehicle dimmer wire(ie. car harness orange, radio harness orange/white) DO NOT connect them you will damage the vehicle dimmer circuit. Here is the breakdown of what wire does what: +Red..............12v ignition +Yellow...........12v battery -Black............Ground +Blue.............Power antenna +Blue/white.......Remote turn on Orange...........Dashlight/dimmer Orange/white.....Dashlight/dimmer Orange/black.....Dashlight/dimmer +White............Front left positive -White/black......Front left negative +Grey.............Front right positive -Grey/black.......Front right negative +Green............Rear left positive -Green/black......Rear left negative +Purple...........Rear right positive -Purple/black.....Rear right negative
  • Check the ground wires.
  • There is a troubleshooting law: If you do something and then things go wrong, undo it. Put the old radio back. In the process, you may find what you did wrong. Why did you replace the battery? If you could start the car before the replacement, there was no need to do so.
  • One thing many fail to realize is many of the systems in a car are linked through the radio and the computer. Removing the factory installed radio can cause several systems to quit working. I think it is stupid for manufactures to do this. I would like to change out my 2001 Chevy radio but cannot because so many systems run through it.
