Harnesses:

Route two main wir- ing harnesses from lift to pump module. Connect to mating harnesses at pump.

Beeper/Strobe Alarm and Plat- form Lights:

Connect har- nesses to mating harnesses at pump module.

Threshold Warning Sensor:

Connect both threshold sen- sor mat harnesses to mating Y-harness at pump module (labeled). Both mats must be installed on a flat rigid surface.

Inboard edge of inboard mat must be minimum 18" from edge of finished floor or stepwell.
