I've spent the past several days trying to find a picture of the back of my combo gauge showing the wiring (or a wiring diagram). I have various current flow diagrams and I've found the info for lots of other 914 combo gauges but not for this one (part # 914-641-101-50).

According to the Parts Vault (thanks for the picture - better than I could have done) this gauge was for 74, 75, 76 914/4 2.0 cars which came without a center console. It's mounted on the left side of my dash. Not working properly, but just in case the PO fiddled with it, I'd like to see how it's supposed to be wired before I dive into it.
I'm not an electrical expert, so simpler is better. Can anyone help? Thanks.
