Hi, I just bought an aftermarket stereo and id like to know if anyone could provide me a color code or wiring diagram for the stock harness for my 1993 Toyota Corolla 4dr sedan.

you don't need one, get the metra harness and wire it per the directions included.

This thread has a good colour guide that you could follow:

I bought an after market stereo with an AUX input for $75 at Best Buy and bought an adapter harness plug for it. I didn't have to cut any OEM wires. I just color matched the stereo with the adapter and plugged it into to car. It took me less than 20 minutes to install and saved myself the installation fee at a local car stereo store.

That helped Kiwi i was able to pull some color codes up yesterday but i didnt know what the radio constant 12v+ and the radio switched 12v+ meant. thanks again.

*EDIT* Finished installing my new stereo and new speakers everything is working awesome, next is to replace the door speakers.
