It's fixed!

I pulled the instrument cluster out and discovered it was previously opened. The tach sided of the cluster was not getting ground. The oil pressure/temp side of the cluster had a couple of burned traces on the board. How they got burned I don't know but it looks like someone soldered it back together. Both traces supplied ground to various places. One was the ground contact for the tach and clock as well as the seat belt reminder.

Still have to check on that power driver seat. Thanks again Joe!
