radio help..

ok...the tape player in my car decided to stop working when i went to go use the cd adapter kit for it for a cd player...and my friend said he would fix it for me..when i got it back he said he didnt know how and all i got back was the stock head unit..a sony one..and all the wires clipped out of the harness and the harness missing. can someone tell me or at least help tell me how to hook it back up or where i can get a wiring diagram? i tried earlier and all i managed to do was get the clock working..and that only happened when the key is on. please give me some help. :werd:

here is a good website that can help http://www.installdr.com
