There are 8 wires for the speakers (two wires for each speaker) ground wire, battery 12v, ignition 12v. The new radio might have a wire for a power antenna (not used) The hardest part is to identify what colour wires are which speaker. There may be a diagram for the wiring on the new stereo. You can use a 9v battery to identify the car's speaker wiring. The speaker will make a crackling sound when you connect the battery to the speaker wires. Don't hold it on very long. You can damage the speaker.
