1990 Z24 Headlights

I recently bought a 1990 Z24. The retard that I bought it from ripped the radio out. I installed an aftermarket radio and ever since my headlights are not working. Someone told me it had to do with the wiring for the radio. does anyone know anything about this? Or does anyone have a wiring diagram they could send me via E-mail?

check out the old haynes eh. as for the headlights though. are you sure you connected the right wires together. did you buy a wiring harness for the headunit or did you connect them yourself. Also always check the fuse.

No I dinnot use a wiring harness. The previous owner had already cut all harness out of the car. As for the fuse the a-hole I bought the car from had the fuse for the headlight piggybacked off of another fuse. It's a f-ing mess. I will buy a haynes if I have to. Just thaught I could save a buck if someone had the schematic already.
