How To Install Arb Air Compressor

Switch Loom (180415)

This harness will be separated by three sections:

Isolation: On/Off

Switch one: Rear locker (or front locker if no rear locker is installed)

Switch 2: Front end locker

NOTE – For safety reasons, the front end locker can only be actuated when the rear locker switch is engaged.

If Air Lockers are not installed, Switch 1 and ii can be left disconnected.

If Air Lockers are installed, or the Compressor switch is desired in the cab, feed the switch harness through an existing grommet in the firewall.

Find an adequate mounting location for the switch(es) then pivot them per included wiring diagram.

ii. Locate an ignition/ACC power excursion, minimum 8 amps, using a multimeter. This circuit must just exist alive when the vehicle ignition central is in either the 'ACC' position or in the 'ON' position. Connect the red/yellowish wire to this circuit using a method of your pick.

Notation – This is not an optional footstep. The compressor will not power on if this step is not performed.

HINT – Cigarette lighter or fuse box may be an adequate source.

iii. Locate an illumination circuit (a circuit that powers on when the headlights are engaged) using a multimeter. Connect the blue/white wires to this excursion using a method of your selection.

Notation – If shortening the reddish/yellowish and/or blue/white wires, make sure not to remove the estrus-shrinked inline diode that protects sensitive electronics from electric current leakage.

HINT – Low beam headlamp or fuse box may be an adequate source.

iv. Route the iv loose male spade terminals of the long department of the loom. This connection has been supplied disassembled to help with routing through the firewall or any tight locations.

v. Assemble the 4 spade connectors into the supplied plastic connector housing. Each colour should match; even so, the ruby should connect to the royal. Plug the connectors together.
