To override the default behavior of the center diff lock, you need a center diff lock switch. The wiring harness for the switch is already present in the US 80 Series, and all that is required is to remove some dash components and plug the switch into the harness.
The automatic behavior is
that the center diff will be engaged (and ABS
disengaged) when Low Range is engaged, but the
center diff is unlocked in high range. With the
center diff lock switch installed, you will be
able to engage and disengage the center differential
in high range. Now you may ask? Why do I
need to do this?
Reasons are: Added traction in high range, limping home in hi-range if a drive shaft has been removed and more. In addition if the PIN 7 Mod is done, you will be able to use the switch to lock and unlock the center diff in low range.
This is an oe style switch that fits the rectangular cut-outs on the factory dash. Switch is backlit but it is not oe green. Switches are supplied with pigtail and plug.

This Slee control box simplifies installation and wiring of the factory Toyota electric locking differentials. It uses any on-off switch (including the factory switch) to trigger the locker actuator for engagement/disengagement. Just like the factory computer, we utilize the internal limit switches to prevent any damage from occurring to the actuator motor.
The control box is supplied as a DIY potted unit with wiring pigtails for reliability in off-road conditions. Works with all Toyota electric locking third members ( 8” and 9.5” )
The interior winch control board is based on the circuit diagram as show on the "Interior Winch Control" Page
The board is supplied as a DIY circuit board with pigtails for easy installation.
The AHC (Automatic Height Control) controller enables the owner to overide the automatic lowerings of the vehicle at speed. The vehicle can be placed in the HIGH mode and will remain there. The controller has two settings. OVERIDE or NORMAL. The colored LED indicates the mode selected
The controler is supplied as a complete unit with box and pigtails, or as a DIY board with connectors. The DIY board makes custom installation easier. One example of the install is to use a switch blackoff plate and modify it to fit the circuit board. See photo below.
