You also need the solenoid valve. If you go with the A/C system or small twelve volt compressor(other than ARB's), you will also need a 80-100psi pressure switch from ARB and a storage tank of some kind. If you buy a Power tank, or build your own CO2 system, you need to get a 100 psi regulator. If you run more than 105psi to the ARB, you will blow out the o-rings.
Give ARB/USA a call #206-264-1669, they will have everything you need.
