That's one of the neat features I like about the TR3, the push button
starter. Consider it an anti-theft device. Nobody will figure it out
(unless they already know).

Yup. Sounds like that bit was tossed out during the cobbling together.
The vacuum switch was a piece that was spliced into the top radiator hose.
Actually there are two pieces of hose with the switch assembly in there.
There is also a connection to the over-run valves on the carbs. With this
piece missing who knows how that is plumbed? In fact, who knows what year
carbs you have?

Easy enough to check.

Sounds a little low but not emminent death for the engine. These things
are quite robust.

I guess this is another of the affectations of the '69 the DPO installed.
As I recall, you said the car had a 75 year engine. This engine should
have the three wire switch. The 74 should also have the three wire switch.
I recommend getting a three wire switch and hooking it up the way it
should be.
BTW, I'll bet the anti-run-on system has been stripped from this car. This
is also wired to the oil pressure switch.
But with a three wire harness and a one wire switch you have a one in three
chance that the right wire is connected to the switch.
