Hopefully new speakers will have arrived today and I plan on putting them in tonight. I don't have any speaker adapter harnesses so I was just gonna clip the wires and install connectors.

Are the factory speakers marked + and -?? If not, what colors wires are which? I need to know for all 4 speakers.

I thought someone had posted a wiring schematic in the past but I can't seem to find it.

 

Left Front Pos = Orange w/ Light Green stripe
Left Front Neg = Light Blue w/ White stripe

Right Front Pos = White w/ Light Green stripe
Right Front Neg = Dark Green w/ Orange stripe

Left Rear Pos = Gray w/ Light Blue stripe
Left Rear Neg = Tan w/ Yellow stripe

Right Rear Pos = Orange w/ Red stripe
Right Rear Neg = Brown w/ Pink stripe

This is for the basic audio setup (not w/ DVD Rear Seat system).

Subwoofer (if instld): pos= Brown w/ Orange stripe, neg= Red w/ Black stripe.

This info is from the F150 WDM.

NOTE: The WDM shows all speaker terminals labeled as follows:
1 for Pos side, 2 for Neg side
Whether thats actually on the speakers, I wouldn't know...I still need to replace mine!
