Yes, it may be the oil temp sender. But, I don't have an oil temp gauge so maybe there was something there before. Not sure. Any idea where the oil pressure sending unit would be? Would it be in the block or the head?

It looks like someone did a custom oil filter relocation job on that. Most of the time the sending unit is to the right of the distributer on the rear of the block......in your case it looks like its next to the oil filter. It is about 1-1/2 inches in diameter with a threaded post sticking out the top where th wire attaches. Wire is usually light blue if it is still stock.

The one by the oil filter boss is the warning buzzer sender. Oil pressure is usually by the distributer. Looks like a bell about 11/2 inches dia.
