ARB Air Locker Independent Locker How
The ARB Air Locker system
in its stock configuration does not allow use of the front differential
locker unless the rear differential locker is also engaged. Use of a front
locker has shown to be very beneficial in some cases, thus the desire to
modify the current system. In a single locker system (front only), the
front locker switch will be wired in place of the rear locker switch, thus
no modifications are needed to allow its use.
Parts & Tools
1. A short length of red
wire (14-16 gauge)
2. A single female push-on
connector (14-16 gauge)
3. Butt-connector or splice-tap
4. Wire cutting, crimping
& stripping tool(s)
Modifying the System:
1. Disconnect the vehicles
2. Remove the switches from
their mounting location, wiring does NOT have to be removed from the switched.
3. Remove the solid yellow
wire from the back of the Front Locker Switch, note location.
4. Locate the solid red wire
entering the back of the Rear Locker Switch.
Using a butt-connector:
5a. If using a butt-connector
ONLY, cut the red wire several inches from the switch.
5b. Strip ~1/4" of shielding
from BOTH ends of the ARB system red wire previously cut.
5c. Strip ~1/4" of shielding
from the end of the NEW red wire (not the ARB system wire).
5d. Insert one end of the
red ARB system wire (leading into the ARB harness) into the end of
the butt-connector. Crimp accordingly.
5e. Insert BOTH the other
end of the red ARB system wire (leading to the switch) and the NEW red
wire into the opposite end of the butt-connector. Crimp accordingly.
Using a splice-tap:
6a. If using a splice-tap
ONLY, strip ~1/4" of shielding from the end of the NEW red wire (not
the ARB system wire).
6b. Place NEW wire into
the the splice-tap, and place splice tap over the red ARB system wire several
inches from the switch. Crimp splice-tap accordingly.
7. Locate original location
of solid yellow wire as noted in #2 of instructions. Measure and cut NEW
red wire to be attached here.
8. Strip ~1/4" of shielding
from end of NEW red wire.
9. Place push-on connector
at the end of the NEW red wire. Crimp accordingly.
10. Connect NEW red wire
to the back of the Font Locker Switch in place of yellow wire as noted
