WHen you turn the key to ACC, radio etc get power.
When you turn the key to ON, Ignition gets power.
IF there are 2 ignitions, do both get power at the same time or is there a delay between the two?

When y ou turn the key to START, power to ACC gets cut off while the DC Starter motor gets energized. Does power to 2nd ignition get cut off too during this time?

=============================================

No. It is an IGN, so it is + 12 in "run" and "crank"

IGN 1 and 2, 3 etc... will come on at the same time,.

My car has 2 ignition cables. I connected only one.
However when I remote start, the heater or AC do not run.

I don't know if it is the second ignition powering my heater/AC or an extra Accessories power. Reason why I think this, is because when you "crank" the engine, ACC and heater/airconditionner both go off until the car is back on IGN.
