Connections: Keypad / Controller / Pump Assembly

Step 6: Mount the Controller- Equalizer Part # 2730, 2745 or 2755
(Depending on the
application). The controller must be mounted near to the center of the "X" that the jack legs form. It
must be mounted to the underside of the floor or to a frame or cross member that "reacts" with the
coach as the jacks plant and lift the coach. All 4 mounting holes in the mounting plate must be used.
There is a sticker on the controller indicating "UP and "Front". It is imperative that the controller be
mounted according to this sticker. Keep the controller away from high heat sources or moving
objects.
Step 7 (Keypad):
Fasten the keypad mount in the desired location (near the driver's seat, if
applicable). Attach the supplied wire harness between the keypad and the location of the controller
(see step 3 above). This harness will connect the in-board 4-pin (J-1) connector on the keypad, and
the mating connector on the controller. This 4 pin connector is the only connection made to the
keypad.
Secure the harness with wire ties or loom clamps to the chassis. Refer to the attached diagram.
Chassis interface connections: Please note that Step 8 and 9 are
required. Step 10 is optional.
Note the "break-outs" near the end of the keypad
Step 8 (Keypad Ignition Disable Circuit):
when the ignition key is in the "on" position.
Pink Input
harness. The wire must receive a +12 VDC
Connect this wire to the ignition positive. This will make the wire "hot and will inhibit jack
"
extension when the vehicle ignition key is in the on (engine run) position. This also provides for a
"jacks down" warning in the event of a jack drifting from the stowed position during travel. This
connection is required. Failure to make this connection may create an unsafe condition and may void the
warranty.
Step 9 The Black w/ Yellow Input. Black w/ Yellow
wire must receive a Ground This wire
must be connected to a chassis ground. If this wire is not connected to ground the Engage Park Brake
light will be on and AutoLevel will be Denied.

Optional Park Brake Connection for Black/yellow wire:

Contact your chassis manufacturer to verify park brake chassis connection and location. This
connection must be done by a technician qualified for chassis electrical systems. Most chassis
manufactures are now doing this thru the Dash Module. Attempts to connect this improperly could
lead to dash feed back or other issues. This connection to a park brake signal is optional. If this input
is
not connected to the park brake signal or to ground, AUTO-LEVEL will be continuously denied.
Also, the engage park brake light will be on if the panel is powered up or the key is in the on (engine
run position).
*Note on items 8 and 9: If Black/Yellow is connected to a park brake signal (as in step 9)
and the pink is connected (required) as in Step 8, an automatic "all retract" will be initiated
if the key is turned on (engine run position) and the park brake is released.
Step 10 (Suspension deflate/Inflate):
If chassis is equipped- There are two additional wires that
break out from the harness near the keypad. The grey wire provides a 12 VDC positive output for 2
minutes when the auto level button is pressed. This may be used to deflate the chassis air suspension.
/The Purple wire will provide a 2 minute 12 VDC positive output when the all retract is pressed. This
may be used to inflate the chassis air suspension. The Chassis must be equipped with an electric
for this interface.
dump/inflate system Check with the chassis mfg for the availability of this and
the chassis side of this interface. If the chassis is not equipped or it is not to have this option, tape the
2 wires back to prevent shorting (do not use).
