My 06 Superduty had a plain jane AM/FM stereo. I got a 6CD MP3 replacement from a pick-a-part. I don't know the vehicle it came from, all I can say is that it was an SUV. The radio didn't look the greatest, but it worked. I went back to the junkyard to see if I could get the plug for the AUX line-in. I found a 2007 Fusion that had it so I grabbed the radio, cut the plug that goes into the back and grabbed that too. The line-in was in the center console so I cut that out too. There were seven wires coming out of the radio plug and four coming out of the line-in jack. I connected the four wires because they were the same color on both ends. One was a black wire that ran to a foil shield that encased part of the harness. I guess the other two go to the CAN bus? I don't know, there is no provision for them in my truck. The fusion radio takes a different antennae plug and the face doesn't work. When I plug in the line-in plug that I wired up, it only works on one channel. When I plug it into the radio from the SUV and hit the AUX button, it says NO AUX. Do I need one of those PIE connectors, or is there a way to make my pigtail work?

 

 

The one on the left came with the truck. The one in the middle is the one I'm currently using and came from an SUV. The one on the right came from a 2007 Fusion takes a different antennae but will still work without it hooked up in my truck.
