I have a 2004 Lincoln Navigator with factory Nav and THX audio. I purchased a Blaupunkt San Diego 530 Nav Receiver from Crutchfield. They threw in a Metra 70-5520 wiring harness. The issue is that I wired up the harness to the receiver and I have no sound whatsoever. There is a 5520 factory wiring harness but also 3 16-pin harnesses that I'm assuming is for the amp, speakers, nav (which I'm replacing with the Blaupunkt receiver), but I noticed that the Metra wiring isn't matching with the factory wiring and can't find a harness that is compatible with my factory speaker system. I'm not an car audio guy, so any help would be appreciated.

Update: Turns out I have to completely bypass the THX amp as there is no integration. Axxess use to produce a THX integration interface but discontinued. I have to wire directly to the speakers from the Aftermarket receiver. Anyone having a problem with this same issue here's a link to the wiring information. http://crutchfield.custhelp.com/app/answers/detail/a_id/5941
