I replaced my factory fitted rear locker with an E-locker. I wanted to use the factory locker switch to operate the E-locker so the ABS and ESC will disable when the locker is turn on.
I also wanted the rear diff lock to work in 4H and 4L and to disconnect the buzzer that sounds when vehicle speed goes above 30Km/h when the rear locker was on. Both of these mods can be done to the factory vacuum operated rear locker.
The diff lock control module is located below the radio on the RHS. Remove the glove box, trim above brake pedal, centre console, trim around the radio and then remove the remaining trim below the radio. The diff lock control module is the black rectangle plastic box shown in the below picture.
I used two relays. Relay one tricks the factory diff lock control unit into thinking the rear diff lock is engaged and relay two supplies power to the E-Locker.
Relay one wiring,
Cut the Green wire with a Red trace (pin 9) at the diff lock control unit. Connect the control unit side of the wire to terminal 87. Just tape up the other half of the Green/Red wire.
86 connects to the Blue wire (pin 3) at the diff lock control unit.
85 connects to earth
30 connects to earth
Relay two wiring,
87 connects to the E-locker,
86 connects to the Blue wire (pin3) Same as 86 on relay one.
85 connects to earth,
30 connects to B+ via fuse
