I am new to this forum, which rocks by the way. I am installing a Z2 into my 2007 Expedition, with factory SUB. I got the Metra 70-5521 kit from Crutchfield, though I did not buy the radio from them. (www.pricegrabber.com had the best price I found)
Anyways, I have pretty much everything set up, but there is a 3rd Factory harness which I have no adapters, or connections to hook up to the pioneer. Infact, there are no more wires left from the Z2 to hook up to the vehicle. So my question: Is this normal, i.e. is this the vehicle specific sensors, which the pioneer does not use at all,
