1. Look under dash in towed vehicle driver side for grommets or holes to come through
the firewall.
2. Drill a hole wide enough to route the wiring from the Dash Mount Connector through the
firewall to the battery.
3. Select mounting location for Dash Mount Connector and route wire from inside of vehicle
through firewall into the engine compartment. Use provided grommet to protect wire.
4. Use 2 ¼” screws, 2 washers and 2 nuts to secure Dash Mount Connector to vehicle dash.
THE BREAK-AWAY IS AN IMPORTANT PART OF THE BRAKEBUDDY® SYSTEM AND IS REQUIRED
BY LAW IN MOST STATES. DO NOT OPERATE YOUR BRAKEBUDDY® WITHOUT A PROPERLY
FUNCTIONING BREAK-AWAY.
INSTALLING JUNCTION BOX
1. Find a convenient, sturdy place on the front of your towed vehicle to mount the junction box
(B). This should be installed on the driver’s side of the vehicle if possible.
2. Clean the mounting surface and attach the Velcro patch (A) (Fig. 1)
3. Attach the junction box (B) to the velcro patch (A) so the pin with the ring faces forward and
the wiring harness feeds back into the engine compartment.
4. Place the mounting bracket (C) over the junction box (B) and mark the hole locations to be
drilled and tapped.
5. Remove bracket (C) and junction box (B). Drill marked holes with a 1/8” metal drill bit.
6. Replace the junction box (B) and
attach the bracket (C) using hex socket
head capscrews (D) or sheet metal
screws (E) provided (Fig. 2).

BREAK-AWAY INSTALLATION
NOTE: Please do not drill before making sure there is nothing behind the firewall that
may cause damage to your vehicle.
NOTE: For thin sheet metal or plastic, it may be necessary to reinforce the plastic or thin
metal to ensure bracket will not separate from the vehicle when the break-away pin is
pulled. If you are going to drill through thicker metal, use hex socket head capscrews (D).
You will need to drill a hole using a #25 drill bit and tap the hole using a 10-24 tap.

After attaching your towed vehicle to your coach and all hook-ups are complete, you will need to
attach the break-away cable from the junction box to the motorhome. DO NOT ATTACH OR WRAP
THE CABLE AROUND THE TOW BAR, HITCH OR BUMPER.
1. Attach the small clip on the cable to the loop on the pull pin of the junction box, and then
attach the large clip to the motorhome. The coiled break-away cable fits all applications and
needs no adjustment.
2. Install the BrakeBuddy® in your towed vehicle
3. Before the start of every trip, pull the break-away pin to test that the break-away system
activates the BrakeBuddy®.
4. When the use of the towed vehicle is needed, simply unhook the small clip from the loop on
the pull pin of the junction box. Unplug the power cord from the BrakeBuddy® and the dash
mount. Store power cord with BrakeBuddy®.
1. Lift lever on back of unit to pull handle
up into ready position.
2. Insert “Grey” end of power cord into
front of unit.
3. Attach the lock nut and clevis
assembly to the arm extension.
4 Place BrakeBuddy® in floor of drivers
side towed vehicle.
5. Attach clevis to brake pedal.
6. Move BrakeBuddy® forward until the
arm extension is fully retracted. Make sure the
vehicle’s brake pedal is not being pressed.
7. Adjust the drivers seat forward until it is less
than a quarter inch away from the BrakeBuddy®
handle. Again, make sure the vehicles brake
pedal is not being pressed.
8. Plug in “Black” end of the power cord into Dash
Mount Connector.
9. With vehicle’s engine OFF, push the red
Auto Start Button located on top of the
BrakeBuddy®. The arm will automatically extend
/ cycle 5 times. This will remove any vacuum
stored in the brake vacuum reservoir of the
towed vehicle as well as diagnose any errors in
the system startup.

Adjust the air pressure to match the weight of your
towed vehicle. The braking pressure, or how hard your
towed vehicle will brake in tow, is adjusted by the +
/ - Buttons (A) located on top of the BrakeBuddy®. To
find the correct pressure setting specific for your towed
vehicle, please refer to the Vehicle Weight Formula
chart below. The display will adjust in increments or
decrements of 5 when held down and displays air
pressure from 10 to 75 PSI. After 5 minutes the display
will “power down.” Upon a button press, the display will
“power on.”
Choose your braking technology preference.
Full Braking Technology fully employs the brakes when
activated, taking the entire weight of the towed vehicle
o of the motorhome brakes.
Proportional Braking Technology, when activated,
performs the same braking force in the towed vehicle
that is performed in the motorhome.
Remote:
Install the AA battery (included) into the wireless remote system. Attach nonskid pad to the back
of the remote system. Place remote and nonskid pad on a suitable semi-flat surface. The nonskid
pad will secure the remote system.
If you wish to change the braking technology preference, press the Braking Mode Button (C) to
select “full” or “proportional” braking. The braking preference can be changed while traveling.
Adjust the Sensitivity either on the remote or on top of the main unit. The sensitivity is how hard
you must apply the brakes in the motorhome before the BrakeBuddy® will engage the in your
towed vehicle. The more lights that are illuminated, the easier the BrakeBuddy® will activate. Each
time BrakeBuddy is installed, the sensitivity setting remains in the last used setting. Start at setting
#4 and adjust your preferred setting as you are driving (using the remote).
For Hybrid Vehicles: At 20 PSI hybrid light
will come on. Adjust lower if needed based
on the amount of braking force preferred. (B)
