Well I did it guys. Idk how, but I did it. After a little less than a total of 17 hours of prep time, research time, driving to the store time, shopping time, eating time, errand time, break time, pee time, and install time, my 5701 is installed and functional. Now if only my immobilizer bypass unit would get here...

If anyone needs help with something like this just lemme know and I can halp. I found it extremely difficult to find 04-07 (08 is different apparently) wiring diagrams that would help me, so I had to just wing it a lot of the time. Had to use a 98 GP wiring guide as a sort of reference material. Ugh...
