1991 mr2 turbo aftermarket stereo wireing?

Question

i need help decodeing what wire dose what in the stock harness

Answer 1

CUT THE RED WIRE OR THE BLUE ONE?

Answer 2

Red and yellow are power.

black is ground.

And if you cant find someone with a chassis then your best bet on the speakers is to do one at a time.

Hook up the power and ground to the radio. and then if you have the after market harness then look on the package and find which wire goes to what and then start with the closest one to you and once you find the correct wire disconnect it and mark it or write down which color goes with which other color.

Only do one speaker at a time.

Toyota's are always like that with the after market stuff.

Well good luck.

And if all else fails take it to best buy and pay them to do it.
