Ground Cable Mounting
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.
Ground Cable Corrosion:
When mounting ground
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
floor grommet to pump
module. Connect to mat-
ing harnesses at pump.

(fill with silicone).
Pump Module Mounting
Mount reinforcement “L” bracket
to pump mounting bracket as
shown in Figure K. Secure
pump mounting bracket to floor
using four 5/16" lag bolts.
Check under vehicle for
obstructions before drilling,
cutting holes or installing
floor mounting hardware.
Note: Locate and drill pump
module mounting holes, floor
grommet 3" diameter hole and
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.
Figure N
Note: All
wiring harness
connections
must be
inside the
vehicle.
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
in Figure N (Steps 1-4).
Optional Interlock Kits
Universal Interlock Kit
30940K is available
for easy interface with
vehicle OEM electronic
signals.
Instrument Panel Display
Kit 30938K provides an
LED Panel Display that
interfaces with Braun
Universal Interlock Kit
30940K.
Note: Detailed installa-
tion instructions are sup-
plied with interlock kits.

Jumper Wire
Install black jumper wire
last. Install the black jumper
wire in pump Terminal Strip
terminals 6 and 9 after all

power to the circuit board.
Check floor level and inner roll
stop adjustments as detailed
in Panel 4 before operating
lift with electric pump.

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.
