manual release 7/8" diameter hole before mounting pump.

Cable-activated Manual Release: The T-handle must be mounted inside the vehicle. The cable must operate freely (no kinks or bends). Warning tag 81823 must remain attached to the handle. Remove handle for installation.

Vehicle and Lift Interlocks

The pump module is equipped with a lift interface 9-circuit connector (female socket).

A mating 9-circuit connector (male plug) is supplied.

To meet minimum NHTSA requirements, connect to vehicle inter- lock harness as outlined

Optional Interlock Kits

Optional interlock kits are available. Contact The Braun Corporation for ap- propriate applications.

Pump Ground Cable:

One ground cable is pump mounted. Route this ground cable through the �oor 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.

Note: All wiring harness connections must be inside the vehicle.

cables, remove undercoat- ing, dirt, rust, etc. from framing member around mounting holes. Apply protective coating to mount- ing holes to prevent corro- sion. Failure to do so will void warranty of certain electrical components.

Housing/Carriage Har- nesses:

Route two main wiring harnesses from lift through �oor 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.
