help stereo 1994 plymouth laser

I'm trying to install a stero in a 1994 plymouth laser. i'm having a few issues. first of all the stero was working, but the rear lights and a few of the interior lights weren't either. well I took it out trying to fix the rear running lights after being pulled over by a few cops. anyways, now nothing works at all, I've tried everything. my lights don't work, the stero dosen't work.   any help would be great and i lost the wiring digram that I was given last time i had trouble! \ thanks
