CONTROLS
The Output Control establishes the maximum amount of
power available to the trailer brakes.
As the Output Control is rotated up more power will be
available to the brakes when the brake pedal is pressed or
the manual control is used.
The Output Control would be adjusted during initial setup,
when trailer load changes, when different trailers are used
or to adjust for a change in road conditions.
The Output setting is shown on the digital display when a
trailer is connected and the brake pedal is pressed or the
Manual Control is actuated.
The Output setting is shown as 0 through 10 with 0 being
the minimum and
SYNC CONTROL
The Sync Control is located on the left side of the Brake
Control Unit, forward of the mounting bracket.
The Sync Control adjusts trailer brake aggressiveness.
The trailer brakes become more aggressive as the switch is
moved toward the front of the tow vehicle.
To view the Sync setting on the display, press the brake

pedal (trailer must be connected) and move the SyncControl slightly. The display will change to the Sync mode.
The Sync setting is shown as
least aggressive and
10 through 90 with 10 being the
90 being the most aggressive.
The Sync adjustment has no effect on the manual control.
The Sync Control would be adjusted for individual driver
preference or changing road conditions.
MANUAL CONTROL
The Manual Control is located on the front of the
Brake Control Unit at the right side.
The Manual Control only applies the trailer brakes and used
during initial setup and in situations to reduce speed slowly.
When the Manual Control is pushed to the left, the control
begins to apply the trailer brakes. The further to the left it is
pushed the harder the brakes are applied until the maximum
set by the Output Control is reached.
The Output setting will be shown on the display and can be
adjusted when using the Manual Control.
The Manual Control activates the tow vehicle and trailer stoplights.

DIGITAL DISPLAY
The Digital display shows the Output setting when the
control is activated. It is used to setup and monitor the
Brake Control and can be used when trouble shooting.
SETUP
Preliminary Adjustments:
With the trailer connected press and hold the brake pedal,
the Display will show the Output setting.
Adjust to 2.0 by turning the control up or down as needed.
While still holding the brake pedal move the Sync Control
slightly, the Display will change to the Sync setting.
Adjust to 40 by sliding the Sync Control ahead or back as
necessary.
TEST DRIVE
In an open area, such as a large parking lot, drive forward
and apply the trailer brakes using the Manual Control.
If the trailer brakes are weak adjust the Output Control up.
If the trailer brakes jerk or lockup adjust the Output Control
down.
Repeat this step until firm braking is felt with out jerking or
lockup.
Once the Output is set, drive forward and press the brake
pedal, the tow vehicle and trailer should make a smooth
stop.
If the stop seems slow and more aggressive braking is
desired, move the Sync Control rearward while holding the
brake pedal.
If the stop seems too aggressive adjust the Sync Control
rearward while holding the brake pedal.
After making a Sync adjustment the Display will show the
setting until the brake pedal is released.
Make several stops at various speeds and adjust the Sync
until stops are smooth and firm. Slight adjustment of the
Output Control may also be desirable.
NOTE: If any problems occur during Setup refer to the
Trouble Shooting section of these instructions.

USAGE TIPS
Light pressure on the brake pedal will activate the trailer's
brakes with no effect on the tow vehicle's brakes. This is
useful for gradual slowing on steep grades or before stops.
Periodic adjustment of the Sync and Output controls may
be necessary to correct for changing road conditions, trailer
loading, brake wear, and/or driver preference.
On some vehicles, operating the Brake Control's Manual
control will not disengage "Cruise Control."

WIRING
WARNING: Do not connect the black "BATTERY" wire to
the fuse panel or tie into accessory wiring. Connecting
to existing wiring may damage vehicle wiring and
cause trailer brake failure.
FOR TOW VEHICLES EQUIPPED WITH FACTORY TRAILER
TOWING PACKAGES: Wire per tow vehicle
manufacturer's instructions.
NOTE: Make sure that the tow vehicle's Brake Control
Battery Feed circuit is capable of carrying enough
current to supply trailer brake requirements (check tow
vehicle manu- facturer's instructions and trailer brake
manufacturer's information). If the circuit does not meet
the trailer's requirements, wire directly to the battery per
through 7.
steps 1
FOR TOW VEHICLES WITHOUT FACTORY TRAILER
TOWING PACKAGES:
1. Disconnect the tow vehicle's negative (-) battery cable.
2. Mount a 30 Amp auto-reset circuit breaker as close to the
positive (+) battery terminal as possible. Using 10 Ga.
stranded wire and crimp type ring terminals connect the
"BATT" side of the circuit breaker to the positive battery terminal.
NOTE: When passing wire through sheet metal always go
through an existing grommet, add a grommet or use
silicone rubber to insulate the wire from the hole
3. Feed one black and one white, 10 Ga. stranded wire from
the Brake Control location to the tow vehicle's battery area.
4. Connect the black wire to the "AUX" side of the circuit
breaker with a ring terminal.
5. Connect the white wire to the negative battery post with a
ring terminal.
6 Attach the Control's black "BATTERY +" wire to the wire
(black) connected to the "AUX" side of the circuit breaker
using a butt connector.
7. Connect the control's white "GROUND" wire to the wire
(white) leading from the negative battery terminal with
another butt connector.
IMPORTANT: A brake control that is not properly grounded
may operate intermittently or not at all. Recheck
sure that the white "GROUND -" wire is connected to the (-)
negative battery terminal and that the black "BATTERY +"
wire is attached to the (+) positive battery terminal.

8. For tow vehicles other than 1989-91 Ford E and F
series trucks and vans:
Determine which side of the stoplight switch is the cold side.
To determine the cold side probe the terminals of the switch
with a test light until one is found that is only on when the
brake pedal is depressed.
Using the wire tap provided, splice the brake control's red
"STOPLIGHT" wire to the attached to the cold side of the
stoplight switch as determined above.
For 1989-91 Ford E and F series trucks and vans with
anti-lock brakes:
Find the crescent shaped connector located on the steering
column (turn signal harness). The connector has two rows of
wires, one row has four wires (inside row) the other has
seven.
The wire needed is the light green wire, second in from the
row of seven (see wiring diagram above).
Using the wire tap provided, splice the brake control's red
"STOPLIGHT" wire to the light green wire.
9. Secure all loose wires with cable ties so that they will not
be damaged and reconnect battery. See vehicle's owners
manual for special re-connectioninstructions.
10. Test Installation:
Without a trailer connected, push the brake pedal. A single .
(decimal point) should light up on the Display.
If the decimal point does not light or if OL or Er is shown go
to the Trouble Shooting section.
BENCH TEST INSTRUCTIONS
1. Wire as shown at right
Set the Output control to maximum (+) and set the Sync control
to minimum (-).
NOTE: If at any time during the bench test, the display shows
OL make sure that the blue "BRAKE" wire is not shorted to the
"-" battery terminal or the white "BATTERY -" wire.
If at any time, the display shows Er return the unit to your
Cequent dealer for further evaluation.
2. Test "Standby Condition"
Hold the red "STOPLIGHT" wire on the "+" battery terminal. The
display should show a single . (decimal point). This indicates
correct wiring and that the control is ready.
Disconnect the red "STOPLIGHT" wire from the battery
3. Test Brake Pedal Activation
Firmly ground the light bulb to the "-" terminal of the battery.
Re-attach the red "STOPLIGHT" wire to the "+" battery
terminal.
The display should step up to 10 and the bulb should start
out dim and slowly get brighter (unhook and re-attach the
red wire as many times as necessary to confirm this)
With the red wire still hooked up, slowly move the Output
Control down to (-). The display should count down to 0 and
the bulb should dim and go off.
Slowly move the Output Control back up to (+), the Display
should go back to 10 and the bulb should return to full
brightness.
Slowly move the Sync Control to maximum (+). The
display should change to Sync mode and count up to 9
