Controller
NOTE: Prior to starting this portion of the installation, double check that all of the harnesses are properly
and securely connected to the rear jacks, landing gear, and rear sensor.
NOTE: The compartment where the controller will be installed should be as far forward on the trailer as is
possible and the controller MUST be installed in compliance with RVIA Gas Codes, as the controller
connections are not spark-proof.
NOTE: For optimal performance, the controller should be positioned directly in the center of the trailer, but
may be offset if necessary. The arrow on the label of the controller MUST point to the front of the
trailer (Fig. 12).
NOTE: There are 4 different options for the controller, depending on whether a 4 point or 6 point system
is being used and whether a Rev. A or Rev. B controller is being installed. PN 433943 is the 4 point
controller and PN 433940 is used for the 6 point controller. Rev. A controllers have an A on the
serial number sticker and black Lippert part numbers, while Rev. B controllers have a B on the serial
number sticker and blue Lippert part numbers. The serial number stickers are located in the top left
corner on the back of the controller.
NOTE: Some 6 Point controllers do not have orientation arrows for the front of the trailer. When installing
those controllers, ensure that the port labeled "LEFT FRONT" is pointing to the left-hand front of the
trailer. This will ensure proper orientation and function of the controller.
1. Measure the ceiling of the compartment where the controller will be placed and mark the center point
on the ceiling.
2. Using four #8 x 1” wood screws (Fig. 13B), attach the controller (Fig. 13A) to the ceiling of the
compartment, centered over the marked centerline of the compartment (if possible).
3. Attach the power and ground harnesses to the corresponding posts on the controller and then
connect them to the correct posts on the house battery.
4. Connect all jack harnesses to the appropriate connectors on the controller.
