What he said. I think it's intended for folks going Ice Racing or something; my car starts just the same as it does in summer with ice on the windshield and the TTS completely disconnected.

The cold start valve circuit is powered from a terminal on the starter solenoid. The thermo time switch (on the chain case) completes the circuit by providing ground whilst the car is cranking on the starter, if it's cold enough (doesn't close until it's below the cut off temperature).

That injector is plumbed into the regulator return side and just dumps raw fuel into the manifold as long as it is powered and there is fuel pressure - however, there's a heater in the thermo time switch so it'll only do that for a few seconds, to prevent flooding.
