1981 300TD (Yes, it's a wagon) Electrical Diagram
 

Trying to track down an electrical diagram for my 1981 300TD.
The diagram in my aftermarket repair book doesn't look right at all.

I posted earlier about a strange electrical anomaly: half my power equipment went out while driving, and I'm trying to track down what all those items have in common (windows, dash power equipment, turn signals), and I'm having no luck. If anyone had a diagram, I'd be real grateful. Thanks!
