Those looking for the temp switch need to follow the line coming from the bottom of the either solenoid, you'll find it threaded into a water jacket. The solenoid will activate at any temperature but the valve will keep it from injecting into the intake manifold above certain temps.

Looked at the wiring diagram again.....sure enough, it shows a "thermal switch" in the ether circuit....I'd overlooked it before.
