I dont know which color wires are for what!

Question edited for a lot more clarity.
Question moved to model category.

A Service Manual, to rent or buy is the best way.

read (you meant main harness to radio sub harness.)
and car may have 5 or more harness for 5 or more very complex radio head end options new,so only the real service manual covers all that for sure,or if lucky 2nd fiddle here.

Go by a stereo shop and get an adapter for your car. It connects all of the correct wires to the aftermarket radio without damaging or removing wires from old connector.

does this model have the built in amp? brownred may be the clock. do you know what each of the wires on the stereo controls? if you know this i can help you.

either way give me a list of the colors you dont know

every vehicle is different. If you get a radio harness (just plugs into the factory plug) from an automotive store the colours will correspond to the aftermarket stereo unit
