wire diagram?

need one for a 85 ranger. going to wire in a stereo for my buddy, and need to know whats what.

you can figure out the wires with a volt meter and a double a battery, i just had to do this to my daily. someone had cut the plug out of it and had no diagram. the power wires are obvious. but all you have to do is take a double a battery and put one of the speaker wires to one end now take the other ones one at a time to the other side until you hear a little like pop noise. those two wires go together for that speaker. note which speaker it was. do this for the other ones until you have them all figured out.

ya, thats old skool too! just thought someone might have a handy write up already. i knew about the battery deal, and i suppose the power wires wont be too hard to figure out.
