Hi, I am in the process of putting in a diff cooler in my car very similar (if not exactly) like the ACR-X cooler. The problem that I have run into is the switch to control the oil pump. The factory part number is P5154012 but there are no assets anywhere and none in the pipeline. It is a 3/8 pipe with 2 terminals on top. I can find single terminal temp switiches but not 2 terminal. I believe the reason for 2 terminals is that the diff is not grounded to the car, where if it was a single would work. Anyone have a source for a 3/8 pipe 2 terminal switch that comes on at 185 degrees? thanks Steve A.
