I have a 2009 Journey sxt. It has the standard six disk dvd radio. I purchased online the mygig reu with remote display screen. The problem is it did not include the wiring harnesses.On the back of the radio there are places for four harnesses to plug in I know that the radio harness will plug right in, and the small one in the middle is for the uconnect, the other larger one will go unused it is for the rear entertainment and the rear camera. There is a smaller one next to the antena connectors that runs to the remote diplay screen. The only harness that I am missing is the small one for the remote screen. Does anyone know where I can purchase one, or have any ideas on fabricating one. My second problem is on the screen there is a place to plug in the harness from the raio, but there is another small female connector on the back of the screen, and I have no idea where it goes or what it is for. Does anyone know what its purpose is and how I can get the harness. If anyone can help or has the REU and can look to see where it goes I would appreciate it. Also after connecting the mic and installing the radio will I need to have it starscanned for the radio or the uconnect to work. Thanks

I have a 2009 SXT. It currently has cloth seats, and I have the opportunity to purchase heated leather seats from a wrecked vehicle. My question is this does anyone know if all the wiring is already inplace for the seats and switches or will I have to purchase the wiring harnesses ?[
