This is the solution of ICS standalone power up without car.
First, need 12V power supply (not car battery!!!
). I recommended PC ATX power supply with little modification:
If you can't modding the ATX power supply, just make short circuit green and any black cable on the ATX motherbord plug, and the ATX power supply start
-> now have protected 12V (from yellow+black).
