Hello, I have an older Kenwood unit in my jku that had navi problems. Got a used pioneer from a buddy. Hooked it up with the pac unit and steering controls and got it Working. Stupid me then started mounting it with power on. Then it died when i was mounting it. Found a lose power wire on the pioneer that my buddy had to a backup cam. That might be the reason for the problem. Tried the Kenwood and It was also dead. Must be the pac harness, jk harness or fuses ? Tried changing the green pos12 fuse and fuse in pac harness but still dead. The pac harness fuse is 1a but I tried a 5a fuse. Could that be it ? Any other fuses ? Need urgent help before roadtrip.
