I'm installing a Kenwood GPS double din in my father-n-law's 08 F250 SuperCrew and have a few questions. First off, the stock AM/FM/CD player had two plugs. One with 12 or so pins and a smaller one with only 7 pins. The only harness I've seen is one that goes to the 12 pin connector. I cannot find what the small harness controls. Does anyone know and is it needed? Second, can the factory rear-view camera be connected to the unit. Its a Kenwood DNX5140 and has a plug for a rear-view camera. I tried searching for a PAC adapter to convert the factory signal but couldn't find one either. I'd appreciate any help.
Thanks

 

That second harness is for factory Sat/Ipod.

I think there are some on here that have converted the factory cam to work aftermarket. Do a search.
