Electronic Control Unit, IE the computer, mounted on right side up
where the air intake snout goes to, big electrical connector goes
there

Nope this is the silver part mounted on the plastic air filter intake
box at the upper end of the rubber snorkel pipe going down to the
throttle valve which is what you are talking about.

This misnomer is cause the Thermo-time switch is also used in water
pumpers, it is a bit hard to find, as it resides under the air
distribution manifold (the clack thing the 4 intake pipes come out of)
If you look behind the distributor, under the manifold, under the cold
start valve on the manifold you will see an electrical connector
attached to something, this is the thing, its on the left side as
you look at the engine, now the part it controls, the aux air bypass
regulator or whatever you wish to call it is on the right side on
the block in back of the distibution manifold.
