Never have found good wiring diagrams for stereo's. Bought them and color codes didn't match. I have mitchell and alldata at work, they don't match. I wire them in with a volt/ohm meter. I find B+, Then hook ignition the the heater control wire. Ohm out the speakers. Thing is, you have infinity. You'll have to find the amp and cut the speaker wires and patch them there also, first. Just a note.. All speaker wires are twisted/paired wires. Cut the tape back 4 to 6 inches to find them. Another note. The speaker wires from the stereo to the amp will be a set of colors. From the amp to the speakers will be different colors.

There will be one on each side of the lower part of the engine on the catalysts, and then there will be two more on the exhaust tubes roughly halfway between the engine and the muffler. You should be able to look at the top of the engine and see four connectors with colored braided wires. They should be white, red, blue and black. You can trace those wires directly to the O2 sensors. 

Check here, this guide might have what you need.

I have the file on my other computer - search other bulletin boards. Check with Crutchfield help desk.

Input wires are the speaker wires from the Amp head/receiver (so you can go to a BestBuy and ask them for the speaker wire colors). Black is ground. Yellow/black is main power. Blue/white is turn on wire. If in doubt take off the door panels and look at what color wires go to the speakers.
