97 cavy radio harness help

ok my friend got a 97 cav and only one speaker worked and it would turn off when the lights were turned off. i know how to do radios but the problem is is that when i took the radio out it was a mess. they cut the factory plug off the wires so i need to know the colors for the factory harness. im gonna call around too and try to find a cavy at a junk yard and get the plug

I'll see if i can snap a pic for you tomorrow. My car is all torn apart and mine is properly hooked up without cutting everything to shit..l.
