97 caldina i pulled out the factory stereo but cant figure out wat wires are wat has anyone got a solution

I don't know if the American wire harness is the same as the euro but atleast in the euro one the colors are as follow,

right front speaker blue and aqua (blue +)
left front speaker pink and purple (purple +)
right rear speaker red and white (red +)
left rear speaker yellow and black (black +)
then you should have 4 -5 wires left the gray one is ACC (ignition remote)
the blue one with the yellow line is constant +
and then thy heaviest gauge wire left is -

these colors are written here by memory i can not say if they are 100% correct, i know the rear speakers are 100% i know the pairing of the front speakers are 100% i think this is the polarity of the speakers, ether it is blue and purple or pink and aqua that i know for sure, and the ACC and constant I'm not completely sure about, but the colors are as i sayed, one is heavier gauge than the other and that one is constant +, but i recommend that you go and buy a wiring harness or a wiring harness that has the ISO standard end on the of the harness and the touota plug on the other, cus most cd players u buy now a days have the ISO standard plug on them.

You can get something called a wiring harness from Walmart (or any place that sells car audio equipment). you plug it into the factory connection that would normally go to the back of the radio, and it has the wires labeled and color coded with what goes where. most times all you would need to do is match up the colors from the harness to the new radio you're trying to install. it makes it really easy to install after market radios, which im assuming you're trying to do.
