1996 Ford Ranger Wiring Problem

Try these colors: LF: blue w/ orange stripe -   white w/ blue stripe +  RF: white -  white w/ blue stripe +  LR: Red w/ blue stripe -  white w/ blue stripe +  RR: blue -  blue w/ blue stripe +   If these don't match try using a AA battery to find the individual speaker leads. Once you hear a pop check which speaker popped then make sure its cone moves outward when you hear it pop. If its cone moves inwards when you put the battery on the speaker lead then try reversing them and seeing if they pop outward instead. This will find you the + and - speaker leads going to each speaker.
