Hi, if the connector is still there, it is easiest to purchase a ford wiring adapter. The adapter will match the factory wires to an aftermarket stereo. If the connector is gone, see your factory wire colors below. Please let me know if you need additional help or have any questions, and thanks for using FixYa.

It is best to buy a connector pigtail for Ford, but you can wire directly using the below color code for the factory wiring. use the color code from the pioneer to match to the factory wires. If you have more questions, please reply.

Have you removed the original connector from you original stereo? If you still have the original connector in place you can get a new connector from the Ford dealer that will plug into your existing wiring and into your new deck. Ford connections are unique to Ford and you need to adapt them for this application.

Take the car and deck to the dealer and tell them what you need. Everything just plugs in and your original amp and speakers in the car will work.

Having said that there was an adapter available at Wal Mart of all places that did work. You may want to check there.

If you have removed the original connector then you need a wiring diagram.

The amp is located under the rear passenger side window. You need to remove the plastic side wall to expose it if you need access there. You can trace the wiring if needed.

Under the front bottom edge of the rear seat are clips holding the seat in place. Open the clips and the seat lifts off. You can then get to the amp as needed.

check the speakers in the rear deck, in the rear hatch or trunk, often the two wires that come out of the speaker touch if that happens it will short out the speaker drivers in the radio most times no permanant damage will occur. separate the wires so they do not touch,or touch the metal speker base, that may not be the problem but its a start..

djmac62 is also an excellent answer

by the way you tell me that the radio illumination is the gray wire and all of the rest you are wrong. try the correct way red is key positive,yellow is constant power,black is ground,orange is illumination,blue is remote,gray is right front positive and gray black is negative,white is left front positive and white black is negative,green is left rear positive and green black is negative,violet is Right rear positive and violet black is negative,
