I don't have a photo and don't have access to my diagrams but I have done this before.  This is going from memory so I may be wrong.  I think the original gauge cup for the alternator gauge had a threaded ground post on it, which is where one ground wire goes.  The other ground goes to the oil pressure gauge itself.   So you will need the original metal gauge cup(s) to ground it the way it was done at the factory.

The ground is for the light bulb only.

Thanks for the help. I found that I was being apparently overly cautious and did not have the main fuse block as tight as I should. Put some extra turns on it and it had power. Also once figured out I needed the 4plug that goes back into itself on the firewall I had ignition. Buying one in parts with cobbled back together wiring to go by has been interesting. Again thanks for the help and ideas.
