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. With the center diff lock switch installed, you will be able
to engage and disengage the center differential in high or low range.
Now you may ask? Why do I need to do this?
Reasons are: Eliminate
drive train windup when maneuvering heavy trailers in low range, added traction
in high range, limping home in hi-range if a drive shaft has been
removed and more.


We have added pigtails to the switches for easier installation.
These switches can be used with Slee Auxiliary Light Install Harnesses.

The interior winch control board is based on the circuit diagram as show on the "Interior Winch Control" Page
The board is supplied in a potted enclosure with pigtails and connectors 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.
