Introduction
The Ground Control® 3.0 5th Wheel Landing Gear operates independently on uneven terrain. Raise and
lower the front of your RV quicker and easier than ever, with the push of a button. Power operation
eliminates the need for manual cranking. The 5th wheel landing gear system can be upgraded to a fully
automatic 6 -point leveling system.

The “CAUTION” symbol above is a sign that a safety risk is involved and may cause personal injury
and/or product or property damage if not safely adhered to and within the parameters set forth
in this manual. Always wear eye protection when performing service, maintenance or installation
procedures. Other safety equipment to consider would be hearing protection, gloves and possibly
a full face shield, depending on the nature of the task.
Resources Required
Moving parts can pinch, crush or cut. Keep clear and use caution.
Installation of Prep Kit
Switch Panel Installation
1. Determine where to mount the switch panel. The switch panel should be mounted in a compartment
on the passenger or driver's side of the 5th wheel so the operator will have a view of the coupler while
using the switch panel.
2. Cut a hole in the wall of the compartment 3 3/8” wide by 2 3/4” high (Fig. 1) so the top and bottom
horizontal cuts are parallel to the floor of the compartment.
All electrical wiring harnesses shall be loomed and secured to prevent possible damage and
installed in accordance with RVIA electrical standards.

3. Feed the two landing gear harnesses ends (Fig. 2A) through compartment hole and attach to the
appropriate switch panel (Fig. 2B) harness receptors, see Wiring the Switch Panel and Landing Gear
and Wiring Diagram sections for complete wiring instructions.
4. Place the switch panel plate (Fig. 3A) centered over the the compartment hole (Fig. 3B). Attach the
switch panel plate with four #8 x 1" screws (Fig. 3C) or screws with sufficient length to thread into the
compartment wall.

Wiring the Switch Panel and Landing Gear
NOTE: Circuit protection is not supplied. LCI recommends a 30 amp auto-reset circuit breaker for this
system and prep a 50 amp circuit breaker, placed in line with the power source for the future
upgrade installation. See the Wiring Diagram section to complete these steps. OEM will need to
supply miscellaneous wiring and wiring connectors. A minimum of 6 AWG wire is needed on all
power and ground wiring.
1. Connect the positive wire from the switch (Fig. 4C) to the 30 amp auto-reset circuit breaker.
See the Wiring Diagram section.
2. Connect the wire from the 30 amp auto-reset circuit breaker to the power source.
3. Mount and prep a 50 amp circuit breaker to be in line with the power source. This 50 amp circuit
breaker will be used for the future upgrade installation. Prep wire from the 50 amp circuit breaker with
a bell cap end. See the Wiring Diagram section.
4. Connect the negative wires from the switch (Fig. 4A) to the negative terminal of the battery.
5. Plug both passenger's side and driver's side harnesses into their respective connectors on the
switch (Fig. 4B).
A. Connect the driver side landing gear harness red wire to the terminal (Fig. 4B).
B. Connect the driver side landing gear harness black wire to the terminal (Fig. 4C).
C. Connect the passenger side landing gear harness red wire to the terminal (Fig. 4D).
D. Connect the passenger side landing gear harness black wire to the teriminal (Fig. 4 E).
6. Connect the positive wires from the switch (Fig. 4F) to the 30 amp circuit breaker.
7. Plug both passenger's side and driver's side harnesses into their respective landing gear jacks, see the
Wiring Diagram section.
NOTE: Only the two-wire connector off of the landing gear motor will be used for the switch panel harness.
The other wire connection from the motor is for a future optional leveling system.

Middle and Rear Jack Harnesses
1. Lay the controller end connections (Fig. 8A) of the four jack harnesses in the bottom of the same
compartment as the rear sensor harness.
2. Run the jack connection ends (Fig. 8B) of the jack harness to the future jack locations through the same
compartment hole as the rear sensor harness. Run the harnesses to their respective jack locations, and
out through the chassis penetrations (Fig. 9A) above the jack brackets (Fig. 9B).
3. Make sure there is plenty of jack harness (Fig. 9B) length out from the chassis hole to attach to the
future jack motor and loop the jack harness end back into the chassis penetration (Fig. 9A).
4. Use seal foam to fill and secure the jack harness wire in the chassis penetration location (Fig. 9A).
Rear Sensor Harness
1. In the same compartment as the switch panel, create a separate hole that will allow access to the
inside chassis area or use any gap in the compartment walls.
NOTE: Allow ample harness excess at both ends to ensure room for future installation connection to the
controller and sensor.
2. Lay the controller end of the rear sensor harness (Fig. 5) in the bottom of the compartment and
run the opposite end of the harness through the inside bottom of the underbelly to the rear center
of the underbelly.
3. Cut a small slit in the underbelly (Fig. 6A) to allow access to bring the rear sensor harness end (Fig. 6B) through
the slit in the underbelly.
4. Loop the rear sensor harness end (Fig. 6B) back into the underbelly slit (Fig. 7A).

Operation
Prior to Operation
The landing gear system should only be operated under the following conditions:
1. The trailer is parked on a reasonably level surface and the tires are chocked.
2. Make sure all persons and property are clear of the trailer while the landing gear system is in operation.
3. Make sure battery power source is fully charged.
Operating Landing Gear
1. Extend both landing gear to the ground by pulling the quick release bolt-on pull pins (Fig. 10A).
NOTE: If the front of the trailer is above level, do not extend the inner legs to the ground. The trailer cannot
be leveled if the front is above level.
2. Make sure the bolt-on pull pins are inserted fully through both sides of the tube.
3. Press and hold the arrow up or arrow down on one or both sides of the landing gear switch panel
(Fig. 11) as desired.
NOTE: For retracting, be sure to hold down the switches until both landing gear are fully retracted before
pulling the bolt-on pull pins.
4. When the landing gear has fully retracted, pull the bolt-on pull pins and slide the inner legs into the
outer landing gear legs.
5. Make sure the bolt-on pull pins are inserted fully through both sides of the tube upon completion.
Never attempt to operate the system without the footpad properly secured or severe product
damage, serious personal injury or death may occur. Electric landing gear is designed for vertical
operation. Excessive side loads may cause damage to the landing gear. The bolt-on pull pin MUST
be inserted fully through both sides of the tube prior to use. Retract landing gear completely prior to
moving the trailer, including retraction of the bolt-on pull pin inner leg.

Troubleshooting
Manual Override
Make sure the trailer is supported at both the front and rear with jack stands before performing any
troubleshooting or service to the trailer. Failure to do so may result in death or personal injury.

NOTE: For ease of manual override it is recommended to unplug the power harness to the motor prior to
performing the manual override procedure.
NOTE: Use of a 12-18 volt cordless screw gun or pneumatic screw gun is acceptable to manually override
the jacks. Do not use an impact screw gun to perform any of the override procedures, as this may
damage the motor.
