[89_coupe]

i need help...
where can i get a free diagram of the stereo wiring for a 1989 lx???
there's no plug on the end of it, and it seems to be having problems!
when i turn the stereo on, it works fine, but no memory.
both power wires only come on when there is power supplied by the ignition. when i turn the lights on, the stereo goes out. ive installed many stereos, and never run into a problem like this. can anyone help me????
oh yeah, no dome lite either, but it works when i hook it to a speaker lead!!!
WTF????
