Did you cut off the wiring harness plug? Ooo, bad move. Never do that, always purchase an adapter. Here, this is all I know: 1990-91 Ford Explorer Stereo Information

when i got to the car all the harneses where already cut. but my question was how to test wires to find which one is the speakers? because none of the speaker wire colors in that diagram, match the wires in the car.

Then the vehicle probably has the "premium sound system" with external amplifiers, so there are no speaker wires at the old HU location. I recomend you purchase the Ford wiring diagram book for the truck.

In general, speaker wires in OEM wiring harnesses are matched color pairs, with one wire being solid and the other being striped. Identify the pair (such as purple and PURPLE / white) and test continuity between them. You should read 2 to 6 ohms. Then you can "pop" the speaker with a battery to ensure you actually have a speaker pair and to identify which one it is.

how do you do that. just hook the positive to the positive side of a AA and negitive to a negitive??????

Use an old 9V battery.....much easier to hold, and NO it won't hurt your speakers.
