A cable should run to a pulley wheel on the left top of the steering bolster. Pulling a handle on the left lower part of the dash out 1/2 way and turning 1/4 turn to lock it out gives auto diff lock, pulling knob fully out gives full diff lock. The knob is connected to the pulley by a wire cable and returned to diff lock off by a spring by the pulley wheel.

This clamps 2 brake discs together locking the left diff quill shaft to the diff carrier via a shaft running up the middle of the left quill shaft.
