Days EQUALIZER SYSTEMS EQ Smart-Level Installation/Operation/Warranty Manual page 10

The below items are designed primarily for motorized vehicles. When installing on a trailer the Ignition
disable is not required and the wiring may not be present in the supplied harness.
• If the pink wire is present, just tape it back.
• If the black/yellow wire breakout is present it will need to be connected to a ground source (this is
pre-connected to ground inside of many harnesses designed for trailers).
It is possible to use these disables on a trailer as an interlock that will prevent extension operation, but this
is not required for most installations. The use of these "interlocks" is at the discretion of the trailer/vehicle
manufacturer. Call Equalizer Systems for further information.
Please note that Step 1 and 2 are required on motorized units.
Step 3 is optional and generally is only used on motorized units
Step 1 - Keypad Ignition Disable Circuit
• Note the "break-outs" near the end of the keypad harness. The Pink wire must receive a +12 VDC
input when the ignition key is in the "on" position.
• Connect this wire to the ignition positive. This will make the wire "hot" and will prevent 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 on motorized vehicles.
• Failure to make this connection may create an unsafe condition and may void the warranty
(on motorized units).
Step 2 - The Black/Yellow Wire Must Receive a Ground Input
• This black/yellow 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 Auto Level will
be Denied.
Step 3 - 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 manufacturers are now doing this through the Dash Module. Attempts to connect
this improperly could lead to dash feedback 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).
