Pump Ground Cable:

One ground cable is pump mounted. Route this ground cable through the floor grommet and con- nect to a vehicle framing member (see Figure L).

Vehicle Battery Ground Cable:

A ground cable (minimum 2 gauge) must be connected from vehicle battery negative post to the same vehicle framing member the pump ground cable is attached to.

Housing/Carriage Har- nesses:

Route two main wiring harnesses from lift through floor grommet to pump module. Connect to mat- ing harnesses at pump.

Beeper/Strobe Alarm and Platform Lights:

Connect harnesses to mating harnesses at pump (labeled). Detailed installation instructions supplied with kits.

Threshold Warning Sensor:

Connect harness to mating har- ness at pump module (labeled). Mat must be installed on a flat rigid surface. Inboard edge of mat must be minimum 18" from edge of finished floor or stepwell.
