Hey quick questions guys! The Pac harness has two yellow wires for the +12V and the Pioneer harness only has one... do i connect the two yellows to the one yellow or does on split off to somewhere else? And same with the ground black wires... do i connect the two blacks to the one black or does one slpit off and get grounded? And the Pioneer harness has a mute wire and the PAC harness doesnt... why is this? And do i have to connect the parking break wire or will video not work at all? Other than that all the wiring is ready to go!
