Due to the double sliding doors for rear seating, there is no easy way to replace the speakers in the 2000 Ford Windstar I drive. I shimmied up a small speaker box for the trunk and wired them through all that plastic molding. There is not really any good wiring diagram for the head unit thus I have made this instructable on how to wire those back speakers.
THIS INSTRUCTABLE IS FOR THE 1F2F-18C868-AA FORD STEREO MADE IN MEXICO
To check if this is yours pull it out and check the back.
(update: the sliding doors are held into place by only one screw, the rest just pops off... wish i knew this before i started. the speakers will go well into the 97 grand am i will be getting soon, though)
Step 1: Removing Head Unit
To remove this head unit you're going to need some DIM tools. I made the mistake of pushing them in too far and spent an hour trying to do this. You just barely push them in untill the springs click. Than spread the tools apart a bit and pull the unit out. Pull out the plugs in it, they have little notches on the bottoms, and set this aside.
Step 2: Cutting Wires
left- brown/yellow(negative) and grey/blue(positive)
right- black/purple(negative) and orange/red(positive)
If you choose to rewire the front speakers these are the wires:
left- light blue/white(negative) and orange/green(positive)
right- green/orange(negative) and white/light green
The first color is the wire color and the second color is the color of the stripe on the wire. Cut these and connect the wire to the speakers to it.
Step 3: Plug N Play
Plug everything back in, and don't forget the antenna! Turn the car on and listen to your new speakers. If it doesn't work you may want to pop it back out and check your connections. If it still doesn't work look to make sure you have the same radio because I think the ones with a disc changer has different connections. If everything works blast the music and piss your neighbors off. My speakers have blue LED's in them so i wired those up too. Let me know what you guys think, this is my first instructable.
