The cable here looks like the power cable hookup, so this is a good start. You will need at least three wires from this harness. The red, black, and yellow. If you are only using this as a display and nothing else, you will still need the "Hideaway Unit" to connect up any RCA video. Do you have that piece too? It has a special cable that fits into the large connector on the back of the deck on the left. Without that, I think you may be in trouble.

Most Panasonic simply require you to tune in the station then press and hold the preset button that you want to store the station in. Takes about 4 to 5 seconds to store.
Well Joe, you will.have to do some investigation. Make sure your radio.has both.constant and.switch. power. If power is good, check the speakers by unplugging them and.check the spk. and wires with a batt. or meter. Also, you need to know.if your running an amp. If yes check it for a good hot and ground.
