Before beginning any work, read
these instructions.
Disconnect the chassis battery
before beginning any work on the
Level Best System.
Removing the old control and wiring (Refer to Figure 1 for Steps 1 through 5.)
Disconnect the positive cable from
the battery before beginning any
work.
1. Cut the wires going to the Fluid
Level Sensor approximately 1 to 2
inches from the sensor.
2. Remove the wires attached to the
two small posts on the motor
control solenoid. Leave the battery
cables in place.
3. Remove all the spade connectors
from the valve solenoids. One of
the wires forms a daisy chain
connecting each valve together.
Trace this wire back to its
connection point and remove it.
4. Unscrew the hose clamps
connecting the jack motor control
unit to the motor. Pull the control
unit and all of the wires away from
the pump unit.
5. Cut the yellow wires that go to
each jack leg from the control unit.
Discard the control unit unless this
is a warranty repair, in which case
you will need to ship it back with
the warranty claim RMA.

The control is wired to the pump using one of these two styles of connectors

Installing the new control
1. Check the condition of the pump
motor solenoid by measuring the
resistance of the primary coil. To do
this place an ohm meter across the
two small posts of the solenoid with
no other wires connected. If the
ohms of the solenoid is lower than
4.3 or higher than 14 ohms, the unit
must be replaced before installing
the new control.
For Steps 2-6 Refer to Figure 2.
2. Install the daisy chain harness. This
harness is identified by its red color,
nine spade connectors and one ring
terminal.
2a. Attach the ring terminal to the
bolt on the motor side of the
solenoid. Then attach the spade
connectors to the inside spade on
the valve solenoids working your
way around the manifold from 1T
through 4T.
2b. Attach the next spade
connector to the 4-way valve
solenoid and pass the remaining
section of the daisy chain across to
the 4B valve solenoid. Attach the
spade connector to 4B through 1B.
3. Attach the wiring harness pigtail to
the pump by attaching the wires
corresponding to the valve markings
on the top of the manifold. Wire TD1
will not be connected at this time.
Wire TD2 is not used at all for this
installation so it can be coiled, tie
wrapped and secured at this time.
3a. Connect the black wire with the
ring lug to the ground bolt on the
side of the pump. On some pumps
this ground lug will be on the back of
the motor and have the black battery
cable connected to it.
3b. Connect the red wire with the
ring lug to the pump solenoid on the
battery cable side of the solenoid.
3c. Connect the white wire labeled
SOL + to one of the empty small
posts on the pump solenoid.
4. Connect the 12" jumper wire
included in the kit between the
remaining small posts on the
solenoid and the ground bolt on the
side of the pump.
5. Install the 16' multi-wire harness.
Route the end with the two
connectors that mate to the control
panel through the firewall and into
the dash area near the control panel
location.

6. At the small connector of the multi
wire harness that goes to the
control panel, are yellow, blue and
black wires. The black wire is not
used. Connect the yellow wire to an
ignition source that has 12 volts
when the engine is running.
Connect the blue wire to the park
brake wire. This connection must
show ground when the park brake
is set. In the chassis wiring harness
you will need to identify the park
brake signal wire. The park brake
switch and signal wire will usually
be found on, or near, the park brake
pedal assembly. This wire will show
ground or 12-volts positive when
the park brake is applied, the type
of signal will vary from one type
chassis to another.

Once you have located the
appropriate wire, determine the
type of signal by using a volt-ohm
meter while engaging the park
brake. If a positive signal is present
the use of a relay is required (See
Figure 3). Next you will need to
splice the blue park brake
wire(PKBK) from the control unit
into the signal wire.
NOTE: A majority of new class “A”
motor home chassis are now equipped
with an automatically applied park
brake system. These systems
automatically apply the parking brake
when the transmission is shifted into
park. In the chassis wiring harness you
will need to identify the park brake
signal wire. This wire will carry a
positive 12-volt or ground signal. A
signal wire can generally be found in
one of four locations.
The steering column just below the
head and rim at the upper
adjustment point or at the base just
above the floor line.
The front bulkhead wiring
connector, this connector is located
on the driver’s side of the vehicle
and can be accessed inside the
vehicle under the dash or at the
exterior under the hood.
At the slave cylinder actuator of the
park brake.
And possibly in the transmission
wiring harness.
Once you have located the appropriate
wire, determine the type of signal by
using a volt-ohm meter while engaging
the park brake. If a positive signal is
present the use of a relay is required
(See Figure 3).

7. At the pump manifold end of the
multi wire harness, the wire labeled
(TD 1) is for the jack leg position
switches. The new control requires
that the leg position switches be
wired in series. (See Figure 4)
Attach a yellow 16 gauge wire to
TD 1 at the pump manifold. Run this
wire to the first jack leg sensor and
attach to one of the two sensor
wires. Attach another yellow wire to
the remaining wire at the sensor and
run this wire to the next jack leg and
sensor. Continue this process until
all four sensors are connected.
At the last sensor attach the yellow
wire to the remaining sensor wire
and run the other end of the yellow
wire to the grounding bolt on the
pump and connect with a 5/16” ring
terminal.
8. Check all wiring connections insure
all connectors are fully inserted and
locked. Reconnect battery cables,
ground first and test the system.
Control Panel Installation
One method of installing the control
panel uses a mounting bracket to install
it below the driver’s instrument panel. If
space is available, flush mounting the
control panel into the vehicle instrument
panel is another option.
First, determine where the wires are to
be routed. Look for any existing holes
that can be used to route the control
panel wiring from the pump manifold to
the control panel location. If no hole is
found, drill a 1 1/2" hole through the fire
wall near the selected installation site.
Route the wire through the hole to the
control panel location.

Route the multiwire cable through the

connector into the receptacle on the
back of the control panel shown in
Figure 6. Insert the control panel into
the bracket and attach it with four 1/2"
sheet metal screws (included in the
panel mounting kit).
Bracket Mount Application
Select a position along the lower edge of
the dash that provides adequate surface
area for mounting the bracket and allows
convenient system operation (Figure 5).

Flush Panel Mount
Application (Not shown)
Inspect the location for flush mounting
the control panel and insure that there is
adequate space for the box portion of
the control panel and the multi-wire
cable connections. Using the template
shown below, layout and cut the
opening. Route multi-wire cable through
the opening in the dash and insert the
connectors into the receptacles on the
back of the control panel. The control
panel should fit snugly into this opening.
Remember, it’s easier to cut the opening
too small and enlarge it to fit rather than
to cut it too large and have to fill the
opening back in.
NOTE: When the control panel has
been installed and the wires have been
routed, seal any holes you may have
drilled from the interior to the exterior of
the vehicle with a silicone sealant.
Completing the Wiring
Connections
1. Check that all system ground
harness connections are firmly
attached.
2. The final connection is the 8 ft. red
#4 cable from the pump motor’s
solenoid to the positive terminal on
the chassis battery.
