Oil Pressure switch on TBI Engine

[bradford]

I got a TBI crate motor that Im about to slap in my truck next weekend.
I noticed it had what seemed to be two oil pressure sending units. One on top and one by the oil filter.
I assume it is for the TBI computer.
This motor has the mechanical fuel pump provision on it. I guess because its a crate/replacement engine?
I am putting an Edelbrock manifold and carb on it.
What do I need to do to utilize one of these oil pressure units?
Do I plug one of them? I guess I could use the unit off my current motor?
Thanks

I wouldnt use either one of them. put the sending unit off of your old motor in the same location as your old motor and plug the other hole.

This.


when I took the TBI out of my C-10 [converted] and dropped it in my 1988 K5, I had to relocate the oil pressure sending units. The old 1988 engine had a blockoff cap for the other spot, which I used on the "new" engine.

OK so the one on the side is where I need to put my old one on?

Where ever your old engine had its oil pressure pickup, use that.In fact, if it worked, use the one from your old engine. Figure out a way to cap off the other one. That's what I did.

The one by the filter is for the oil pressure gauge. The top unit is for the computer sending unit.
