Im installing a pioneer in my expy. I can not find the accessory wire for the 12v. I have the ground and power. The harness doesn't match up either.

 

I was doing my mother in laws last night on her 07 expy and noticed that there were two harnesses that plugged into the back of the factory. In laws only bought the bigger harness of the 2 to plug into the factory wiring. I am lost

 

pics?

 

The 07 and 08 require a special adapter. PAC C2R-FRD1.1 radio replacement interface lets you replace the factory radio in select 2005-up Ford, Lincoln, and Mercury vehicles that use the MSCAN databus. You'll still be able to use factory features like Rear Seat Entertainment, Rear Seat Controls, and the THXII amplifier.

 

Thanks Im looking into to that today
