I just bought a 92 that didn't have a head unit at all. The previous owner ripped out the aftermarket they installed and didn't leave the harness or anything, so all I have are 8 wires that don't really match the wiring diagrams I've looked up. There are no headrest speakers, but I found some that I believe were installed by the previous owner behind the seats right in front of where the top rests when it's down. I can't find any wiring for these though. I would appreciate any help you can give me, and pics would be great. I've done plenty of installs, but never with wires missing like this.
