Wire comes from ignition switch connection C goes to oil pressure light. Wire from light to oil pressure indicator on engine. Which is also the ground for the circuit. Another wire also comes off ignition switch at same point is the charge indicator light. This wire then goes to "A" connection on regulator then  to generator.

oil wire is white with red band,  gen wire is yellow with black band. Wiring diagrams are available just about everywhere for sale on the web. If you are going to do a lot of work on the wires it may be advantageous to buy one.

Tom:

It's a 1/4" NPT thread, not 1/8".  Not wanting to start something, just want the right info to be out there.

ok is there a way i can connect the new after market oil pressure gauge to a hole on the block and connect the pressure switch to another hole on the block and if so were would i find these holes

you can put  a fitting that accepts two senders  into the existing hole and run a mechanical and electrical unit  from one point

I just went through all this. I used the front port for my oil pressure gauge and rear,just behind the filter for the warning light switch. The original oil pressure switch was 1/4 inch

pipe and the gauge was 1/8 inch pipe,so just use an adapter. I had originally used a "tee"

but It's to cramped to get at everything. The only hard part was removing the pipe plug,I don't think it had ever been out in 52 years.
