i know where the wire goes in the wiring harness but not in the car the harness go to the tranny but i can not find any where this would go on the tranny

 

Looks like an oil pressure sensor.

 

where would that go in the side of the block ??

 

think it goes in the back of the intake manifold

 

Screws into the block just behind the intake manifold.

 

Not for a 93. That particular one goes just above the oil filter.

 

sweet thank you guys soo much

 

Bingo! we have a winner!

 

If you're talking about SS RRR, then yes we do.

 

i shattered mine while removing my heads. I gave it gentle pressure after loosening with a wrench and bam the black part ripped off. (mine did not have that heat sleeve like in the pic above.) Anybody know where to get one cheap? I was wondering if I should go with a mechanical gauge at this point.

 

You should be able to pick one up for like $30 from your local NAPA or Carquest... Most of them stock them as a "oil pressure switch."

 

ok thanks.

 

Guess, I should have looked at the sig. It still holds true for newer models.

 

In addition to the switches being mounted in different locations in early vs late model LT1's, the switches themselves are different aren't they? I know the switch in that pic appears to be different than the switch I replaced at the rear of my block behind the intake.

Aren't the two oil ports in place on all LT1's, allowing for the use of either switch, regardless of year. You would just have to mess with the wiring, and get the different switch, if you wanted to move it from its stock location?

 

Yes, they are different. The early one uses larger threads. Either place can be used with the right sensor/adapters.
