About the SwayControl
BMPRO SwayControl is a proactive electronic stability control that can
automatically stabilise a caravan/trailer in the event of a sway. It automatically
corrects caravan/trailer sway which can be caused by changing road conditions,
driver error, lateral winds or a passing truck, keeping drivers safe on the road.
The SwayControl is mounted on the underside of the caravan/trailer chassis,
wires directly to the trailer braking system and continuously monitors the trailer
to detect sway. If sway is detected the SwayControl automatically activates the
caravan/trailer brakes to bring them and the vehicle under control.
SwayControl distinguishes between safe maneuvering and dangerous trailer
sway and does not require driver intervention. With independent control of left
and right-hand side trailer brakes, and continual closed loop feedback, the
SwayControl quickly and effectively applies the necessary braking force to the
side of the caravan/trailer where it is needed to correct trailer sway.

Installation Instructions
PERSONNEL
The SwayControl is a safety device which is required to be installed in the caravan/
trailer by suitably qualified service personnel.
To operate correctly, the SwayControl must be securely fastened onto a vertical surface
of a steel trailer. Do not fasten the SwayControl to any other trailer surface that flexes
or moves from wind such as plastic covers or plastic walls.
ORIENTATION
Ensure that the SwayControl is mounted in the correct, UP direction.
The centre of the SwayControl (marked by the orange dot on the SwayControl label)
must be positioned over the centre line of the caravan/trailer.
The bottom edge of the SwayControl (as indicated by the orange line on the bottom of
the SwayControl label) must be mounted parallel to the trailer beam axle.
Figure 2 further demonstrates guidance on mounting the SwayControl to the trailer.
WARNING
For proper operation of the SwayControl, ensure that the electric brakes are
adjusted and maintained in accordance with the manufacturer’s recommendations
in the electric brakes owner’s manual.
MOUNTING LOCATION CONSIDERATIONS
The suggested location for mounting the SwayControl is on the first trailer frame
crossmember, approximately 0.3 to 3.0m behind the trailer hitching point.
The SwayControl must be mounted in the correct orientation (as indicated on the
label), on either the “leading” or “trailing” edge of the crossmember. “Trailing” edge is
preferred, as it provides the best protection from road debris.
WARNING
DO NOT spray high pressure water on the SwayControl. The SwayControl is a
weather sealed, water resistant unit, but it is not designed to withstand direct, high
pressure spray from a power washer.

7
WARNING
When installed, it is essential that the SwayControl is orientated in the correct
direction.
MOUNTING
Mount the SwayControl to the caravan/trailer using the mounting flanges located on
the sides of the unit. Use four #10 self-tapping screws (not supplied) with star lock
washers to mount the SwayControl.
It is recommended that star lock washers are used and that mounting bolts are securely
tightened to hold the SwayControl firmly in position and to avoid becoming loose from
vibration.
WARNING
DO NOT drill holes in the SwayControl for any reason. Drilling holes or puncturing
the unit will void your warranty.

Wiring Instructions
SWAYCONTROL WIRING HARNESS
The SwayControl wire harness has five wires requiring electrical connection (table 1)
and one cable for the status LED light.
When making connections to the caravan/trailer’s wiring harness, the desired
termination is a solder joint. If the connection is not soldered, use the appropriate
size and type of “crimp-type” weather sealed heat-shrink connectors, using the
manufacturer’s recommended crimping tools in accordance with their crimping
instructions.
WARNING
Taking shortcuts when connecting any wires on your trailer only increases the
likelihood that some part of your electrical system will fail.
Make sure connections are durable and sealed against exposure to weather and
corrosive elements. One loose connection can disable your entire trailer brake
system.
WARNING
Failure to use the correct wire may result in poor braking performance or brake
failure. Incorrect wire size may also result in significant damage to your trailer or its
components.
Undersized wire will prevent electrical circuit protection devices such as fuses or
circuit breakers from functioning properly.

WIRING DIAGRAMS
Caravan/Trailer Battery
The caravan/trailer must be equipped with a 12V battery system of greater or equal to
50Ahr.
Ground Connections
The caravan/trailer battery ground, the SwayControl ground and the electric brake
ground wires must all be securely connected a 1.8 mm2 (minimum) wire in order for
the SwayControl to function properly.
These must be all fully grounded to a common point on the caravan/trailer.
Figure 3: Trailer Battery Wiring
Figure 4: Ground Connections Wiring

11
12 Volt Connections
The tow vehicle 12V charge line, the 12V trailer battery terminal and the SwayControl
12V (black wire) must be securely connected together with a 1.8 mm2 (minimum) wire
in order for the SwayControl to function properly. The “hot” wire from the breakaway
switch must be connected to the +12V terminal of the trailer battery.
Electric Brake (Blue Wire) Connections
The tow vehicle brake signal (blue) wire must be securely connected to the
SwayControl brake signal (BLUE) wire as well as to the “cold” wire from the breakaway
switch.
Figure 5: 12V Connections Wiring.
Figure 6: Electric Brake Connections Wiring

12
Left and Right Side Brake Wires
The SwayControl operates the left and right side trailer brakes independently in order
to control caravan/trailer sway. Therefore, it is very important the correct SwayControl
wires are connected to the correct side of the brakes.
The SwayControl PURPLE wire must be connected to all left side brakes.
The SwayControl PINK wire must be connected to all right side brakes.
Failure to properly connect these wires will prevent the SwayControl from controlling
trailer sway.

Status Light Module Installation
Once wiring is completed, route the Status Light cable to the front of the caravan/
trailer. Then mount the Status Light module onto a flat surface on the drawbar of the
caravan/trailer using self-tapping screws.
Select a location that makes it easy to see the Status Light when looking at the front of
the caravan/trailer.
Figure 9:Troubleshooting with the Status Light
WARNING
When the caravan/trailer is not moving, every 60 seconds the GREEN light will
turn off for two seconds, then turn back on. This is normal and indicates normal
operation of the SwayControl.
If your notice the GREEN light turning off and on every 60 seconds and the caravan/
trailer is moving, have your SwayControl checked by your local service centre.
SWAYCONTROL SELF DIAGNOSTICS
The SwayControl performs a self-
diagnostic test every time it “wakes-
up” upon receiving a signal from the
brake controller in the tow vehicle. The
Status Light may flash RED and GREEN
approximately six times on start-up then
go GREEN.
Once in operation, the SwayControl
continually monitors the system for
faults. If the system is operating properly
and no fault is detected, the GREEN light
will remain on and flicker or pulse.
If the SwayControl detects a fault in the system, the Status Light will turn RED and the
fault may be diagnosed from the RED Status Light flash sequence. The SwayControl
continues checking the fault status and the RED Status Light will continue to flash until
the fault is corrected. Once the fault has been corrected, the GREEN light returns.
For more information, refer to Troubleshooting with the Status Light.

15
Final Brake Wiring Check and Start Up
To check that the SwayControl is wired correctly:
1. Refer to figure 10 to verify correct wiring on the left-hand side of the trailer.
Ensure that ONLY the PURPLE and WHITE wires from the SwayControl are
connected to the left side trailer brakes and are wired in parallel and not in series.
2. Refer to figure 10 on the following page and verify correct brake wiring on the
right-hand side of the trailer.
Ensure that ONLY the PINK and WHITE from the SwayControl wires are connected
to the right side trailer brakes and are wired in parallel and not in series.
After performing the final brake wiring check, the SwayControl is ready for start-up.
The operational status of the SwayControl is indicated by the LED Status Light. The
SwayControl is in sleep mode if the LED Status Light is off (dark). The SwayControl will
start-up (wake-up) when voltage is applied to the BLUE wire.
Once the trailer is connected to the tow vehicle, apply the manual override on the trailer
brake controller in the tow vehicle. If the SwayControl is installed correctly, the LED
Status Light should start flickering GREEN.
If the LED Status Light does not come on when applying the manual override on the
brake controller, refer to Troubleshooting with the Status Light to diagnose potential
faults in the installation of the SwayControl.

16
Figure 10:Verifying correct installation of the left and right side brake wires.
WARNING
When inspecting trailer wiring, it is very important that the trailer brake controller
wire from the tow vehicle (blue wire) is ONLY connected to the BLUE wire on the
SwayControl AND NOT connected directly to the trailer brakes.
SERVICING
Do not attempt to service the SwayControl yourself, OR dismantle, modify or repair
the SwayControl yourself; this will void your warranty. If your SwayControl requires
