Application: 1973 Buick Electra 225, aka Land Yacht 455 Buick motor, NOT the
Olds version OK.....I am stumped, and have stumped several different parts
What is the switch/sensor doing in the back of the head????? It is a two
device that is located in the rear of the passenger side head.
The switch works on heat. When it is hot, the switch closes, cold...open.
What is it's purpose??
Could someone provide a part number of something too??
More info..the two wires are brown, and there is a similar sensor on the
opposing head, same location.....single "nub" similar to the old style oil
