5.2.2.2 Dual Air Locker System
! If two Air Lockers are to be installed in the system, ARB
recommends that the switches and solenoids be wired according to
figure 20. For safety reasons, this configuration allows SOLENOID
2 to be actuated only if SOLENOID 1 is already on.
! Attach the “REAR AIR LOCKER” switch cover to SWITCH 1, and
the “FRONT AIR LOCKER” switch cover to SWITCH 2.
NOTE : Refer to figure 18. for the correct switch terminal
identification and switch orientation.
! Configure SOLENOID 1 as the air line leading to the rear axle Air
Locker, and SOLENOID 2 as the air line leading to the front axle Air
Locker.
