Select a location to mount the 12 volt compressor assembly. The location should be away from heat sources, contamination and 
must provide the compressor with a good electrical ground by attaching the compressor grounding wire to a good ground source. 
Route the compressor power supply to the positive battery terminal and connect, secure wire with tie-straps supplied.

NOTE: A remote breather kit for the compressor intake must be used if dust or road spray is present near the air 
intake filter. Pacbrake part# C11620 is available and must be ordered separately.

Switch location can vary depending on customer choice or the availability of space. Choose a location which is convenient to the 
driver. Pacbrake offers a gear lever mounted switch for manual transmission equipped vehicles. (It is a good idea to consult the 
operator of the vehicle for their preference.) Most importantly, locate an area which is free from obstruction. 
Remove dash panel below steering column. 

Note the panel is double wall construction and the inner wall will require modification to accept the dash switch. 

Drill a 1/2” hole, install the switch and wires as shown in the schematic for your application. Locate an ignition 12 volt positive 
source, attach the T-tap provided.Connect to black fused harness. Connect the yellow wire, routed into the cab earlier, to the dash 
switch.  Attach the green wire to a good chassis ground. Reinstall lower dash panel.
