Where is the oil sender unit on a 92 SSEi and what the heck does it look like? my grandad went to the junk yard with me today and got one out of a 92 SE but looks nothing like the one i almost bought at the autopart store that looks like the one on our 94 SSE which i know what and where on that, but this one has me lost please help

Oil pressure sender/switch looks like a cylinder about 1 1/4" in diameter x 4" long with one threaded end and electrical connector at the other. It'* located a bit below and to the left of the water pump pulley on the back side of the motor. The senders are very similar from year to year in physical dimensions but differ somewhat electrically. I have a sender from a 90 LN3 engine installed in a 97 L67 engine. It was a direct screw in and even the electrical connection was the same size (but with two fewer electrical contacts).
