The vacuum valve on my truck has just 2 wires controlling it. The specific bulb that I used was a T3-1/4, just put in parallel with the vacuum solenoid. It works because my system is just on/off, as far as I am aware.
I don't know how well it would work on a newer car, with % mix control and what not.
