Re: oil pressure unit
Either threaded in the side of the block above the filter or in the top back edge of the block near the distributor. Usually threaded into a tee, elbow, or straight adapter.

Re: oil pressure unit
I installed an aftermarket oil pressure gauge and didn't want to interfere with any of the factory wiring. I added the sending unit in the unused port on the rear of the block by the china wall.
