I only have the 6 speaker setup. I finally just decided to install the Pioneer HU without attaching that plug becuase the Pioneer has a built in amp and everything worked fine...except I've lost the use of the AUX jack in the center console.
I'm replacing the HU on my 2006 SR5 Fujitsu part 86120-52530 out what the 20pin connector is for? I'm replacing it with an older Pioneer DEH P770MP HU and it doesn't have anything like it. I purchased the wiring harness which will work fine, but need clarification as to what that 20pin plug is...
I figure I'll use my first post on this one. I got the weathertech mats and cargo liner for my 06, and they fit perfectly. Well designed, form, fit and funciton. Worth every dollar to keep the the inside clean when the hunting/fishing trips are done.
