Automatic battery Disconnect
If you tow a Jeep Liberty, Jeep Wrangler or any other
vehicle which must be towed with the battery cable dis-
connected, install the Automatic Battery Disconnect (part
number 765).
Fully automatic ‘connect and forget’ operation eliminates
the necessity to discon-
nect the cable — the vehicle
can be towed, then discon-
nected and driven, without
any further adjustment to
the battery.
The Automatic Battery
Disconnect also provides:
1) a constant charged current to the battery while the
vehicle is being towed, preventing supplemental braking
systems or other aftermarket accessories from draining the
battery; and 2) a positive current source for break away
systems or other accessories which must be connected
to the battery.
• preassembled for easy installation
• marine-grade high-amperage solenoid and contacts
• 100% duty cycle
• extends battery life
• works on virtually all 12-volt batteries
brake Pressure Reducer
With the Brake Pressure Reducer (part number 900002),
you can install BrakeMaster in a hybrid, a Hummer H3,
or in any vehicle with an
‘active’ (or, ‘continuous
power assist’) braking
system.
Working in conjunc-
tion with these braking
systems, the Brake Pres-
sure Reducer delivers a
correspondingly reduced
braking pressure that
eliminates over-braking issues associated with these
hybrids and Hummers.
In addition to BrakeMaster, the Brake Pressure Reducer
will work in other supplemental braking systems which use
pressurized air to brake the towed vehicle.
brake-lite Relay
Necessary in the majority of towed vehicles, the
Brake-Lite Relay (part num-
ber 88400) allows the towed
vehicle’s brake lights and
turn signals to both work
in tandem with the mo-
torhome’s, as required by
law.

Stop light switch kits
If a towed vehicle’s brake lights do not function, install
this stop light and 10-amp fuse. With the stop light switch
i n p l a c e ,
t h e t o w e d
v e h i c l e ’ s
brake lights
will work in
tandem with
the motor-
home’s, and
the motorhome monitor will transmit accurate braking
information.
ROADMASTER manufactures stop light switch kits for
a number of vehicles; for the most current list, visit the
ROADMASTER website at www.roadmasterinc.com and
select ‘Products,’ ‘Supplemental Braking Systems,’ ‘Brak-
ing Accessories, and ‘Stop Light Switch Kits.’
Air line tees
If the motorhome's air brake relay valve (or air booster
can) does not have an open
port, use either a ½" tee (part
number 450076) or a 3/8"
tee (part number 450077)
to attach the BrakeMaster
air line.
