SO, i picked up a harness today at the junkyard. (Thanks S&B for the offer...very generous)
It was right up street from work and the Fords are kept up front, so i went on my lunch break (in shirt and tie mind you) and snipped a few harnesses up. Got one set from an explorer and another from a Lincoln LS. Guy even just let me have them
Got home and decided to use the explorer harness since Ford put some crappy foam gooey insulation crap on the LS harnesses all over. Some sort of noise reduction for the interior?
Anyway, only need 2 of the 3 plugs. 1 plug has wiring for the speed volume and steering wheel controls. I might try and hook up the VSS later, but right now who really cares.
The explorer harness only had 4 wires in the "subwoofer" plug, so i simply took one of the plugs I didn't need and removed 4 pins and added them. Simple problem solved.
Now i have my harness. Time to solder up to my Metra 70-1770 Fox body Mustang harness.
plug on the right is what i used to pirate extra pins for my sub harness plug (one in middle)
Plug on far left is the main power + speaker plug. I'll wire in the power and OEM fox speakers here. This way, i'll use the fox wiring to power the tweeters front and rear. Only plan on using front tweeters in the dash locations for now, but want to leave the option open for the rear. SInce i have 90-93 rear panels, but using my 88 lap belts, the upper shoulder belt access hole would make a nice custom rear tweeter location
middle plug will be splices into some RCA's once i figure out how. This will be line out to my 4-channel amp. Will power door speakers and rear hatch speakers.
I REALLY wish i snagged a fox body radio harness while i was there. That way i can plug it into my custom adapter harness and wire in my bench power and grounds and such so i can test it on a bench first. Might go back after this latest snowstorm. They had a few fox 5.0's.
