Now I'm starting to find interesting items...

Started to ring out between the bulkhead connector and the two main plugs for the gauge cluster. Here's the findings so far:

* Position 29 on bulkhead (oil pressure) - Violet on 12-pin
* Position 32 on bulkhead (engine temp) - Gray on 12-pin
* Position 22 on bulkhead (ammeter) - Red/White and Black/White on 12-pin


This still doesn't explain everything, not by a wide mile, but it's a start.

Next, I move to the seat belt buzzer (CI 7). As you can kind of see in the picture, light green wire has been double-spliced and the peach-colored single wire from that connection is running straight down to a mount just behind the ashtray. Somebody has been in here before.

Now, for the real mystery: where is the panel ground (CI 34)? Book says "left mid reinforcement". Can somebody put that into layman's terms for me, please?!
