At this point it was time to install, wire, and plumb the rest of the system. We located the air storage tank and compressor in the trunk using the mounting templates included in the kit. The compressor is wired with a 12-volt power wire of 12-gauge or larger, and a 20-amp fuse is required. The power wire should run directly to the battery, and the fuse should be placed as close to the battery as possible. The red wire from the compressor and the power wire from the battery are attached to the pressure switch in the compressor head.
