In order to determine the correct 12v, 30 amp, ignition activated power source for your Command I Xtreme Duty Compressor with Analog Gauge, Air Tank, and 25' Hose # F2543, you will need to physically test with a multimeter # PT29ZR, or refer to your owner's manual for which circuits come on with the ignition, and which ones are at 30 amps.

Unfortunately, we cannot tell you which circuits those might be, as these will vary from vehicle to vehicle.

I have attached a piece of the wiring schematic and a review video for you to check out as well.
