1994 Corvette oil pressure sensor need help

Hi everyone its been a long time but I'm back and happy to say that I have my rebuilt engine back in the car now.

I need help with a part I think its called an oil pressure sensor. I cant find a detailed photo of it on the net. I need to know how it is put together meaning the 1st peice screws into the rear of the block another longer peice with 2 screw holes screws into it. The sensor screws into the upper hole but the peice has another one that I cant seem to find what goes in it. My question is what screws into that 2nd hole

Thanks again I will kept you posted on the progress.

There are two oil pressure sensors that screw into the adapter, one has three pins GM =10201491 it is the sender for the gauge and is also a switch that provides backup power to the fuel pump in case of relay failure. The second sender has one pin GM 25036935 it illuminates the check gauges light if oil pressure drops too low.
