Wiring A Pioneer DEH P6400

go to store that sells car decks and look for a wiring harness for ur car its about $7 mybe and prettymuch match the colors on ur deck to the harness and then pull ur old deck out and pull the harness from the back the back of that deck and plug that into the wire harness u just bought and hook up the antenna for radio andput the deck into the dash the wire harness should also come with so directions too just in case

You are not going to be able to get the stock changer to work with the Pioneer deck. They are not compatible.

Check on autozone if they got the harnes adaptor

What power input are you hooking it to? Do you mean how to wire it? Or hooking up amplifier?

If you want a user manual and installation manual, you can get them here:

check the wiring loom & pins in the plug.

you must buy a wire harness connector from best buy or another dealer with knowlege and parts available / ps with this connector you just connect the wires from the radio to the connector following the color diagram and then snap on the connector to the car plug and it will work..

shut it off then hold the function button
