Click to view attachment I assume you want to know where it goes on the engine. The wire winds its way from inside the engine compartment down through a hole in the tin (passenger side), across the engine mounting bar to a thing called the taco plate (see photo). The connection on the taco plate is inside the hole and kind of hard to see.
There should/might be a plastic covered push-on connector at the end of the wire that comes out of the hole in the tin. This end connects to the same color wire (grn/blk) coming out of the harnes,s which originates at the gauge.
Do a search for "taco plate AND oil temp sender" for more information. Oh, and let me be the first to welcome you to the Club.
