Aux Air Regulator

Does anyone know where the AAR gets its electrical current from? I assume it is in line with the warm up regulator. Is it in line with anything else?

Starting with the engine cold.
Start valve and thermo-time switch are switched on. The engine turns (pulses are taken from terminal 1 of the ignition coil.) The control relay, electric fuel pump, auxiliary air device and warm up regulator are all switched on.

fig. 2.36, page 66, chapter 11. Solving Bosch CIS Problems

I couldn't have said it better myself.
