Customer Question

I'm trying to diagnose a problem on my 1992 BMW 318ic; the Tachometer, interior lights, OBC, and stereo don't work. All other gauges/lights/switches appear to work fine. I already pulled everything apart, replaced the s.i. board batteries, checked much of the wiring, and tested all the fuses. I thought that the problem was a relay to the OBC, but since my car has no relay (since its just the 6 button obc), I'm at a loss. Please help me isolate the problem.
