You need to get an installation kit that also has the universal wiring harness to connect to the factory harness in the car. That way you only need to match the wire colors of the Pioneer harness to the wire colors of the universal harness and made good connections and insulate those connections. Then the Pioneer harness plugs into the Pioneer radio and the universal harness plugs into the factory harness in the car.

Let me know if this helps, or if you need more help.

    Why the bad rating?

    Didn't this help you?

    If you follow the instructions I gave you could easily install a radio into any car.

    If you don't understand what I wrote, you could ask for some clarification.

    I guess you really don't "GREATLYappreciate" free help.

    I gave you the easiest way to install a car stereo, without even needing to know what each wire is for. If you would rather do it the hard way, I can always tell you what each wire is for. But if you are not going to use a universal installation harness, you will most likely make some kind of mistake and maybe cause some damage to the stereo or the vehicle wiring. I was only trying to help you avoid problems.

    Bad ratings for good free advice makes it very difficult to offer anybody free help. There must be some kind of motivation to work for people for free.

Wiring A Pioneer DEH P6400

If the factory harness is still in tact, you can buy an adapter at Best Buy for about 20$ or ask to see one and write down the pins and wires then match it up and cut n splice to your new deck. Hope this helps
