Isuzu 4bd1t engine

[Driver]

Have an isuzu 4bd1 turbo in my hitatchi digger. Is anyone here familiar with it? Where can I plug in an oil pressure gauge to get the psi it's working at?

There are these little squares in it. I can hardly plug into them?

Take out the oil pressure light switch and plumb the gauge in there instead,or get a T piece and have both gauge and light switch from the one place.

Where is this on the engine? A lot of sensors have been disconnected on this engine already in a previous life.

No offence but If you can't determine the oil pressure switch from looking, probably best to call a mechanic in with a pressure test set.
