Mystery plug. Please help
Can any body please tell me what the 4th skinny plug is on the back of the factory hu? I am swapping out the delco and my harness adaper kit came with the extra (power?) plug, which the new deck doesn't have, should these be paired with something in the 12 pin harness? :?:
Thanks, admitted noobski
