Installation Instructions
1. Electrical connection is required for all
installations. Approximately 25 ft. of
automotive-type multi-stranded 14 gage or
heavier single wire with tough, thermoplastic
insulation meeting SAE standard J558a is
required.
Note: When towing a very light trailer,
Warner Electric System Resistor 1100-41
may be required to properly proportion
braking force between the trailer and the
towing vehicle.
2. Mount the controller on the brake pedal as
shown on page 4. Tighten it securely to the
pedal with the clamp provided in the kit.
Insert the connector end of one hook-up wire
segment into a matching connector
extending from the controller.
3. An electrical socket which mates with the
trailer power cable is to be installed in the
rear of the towing vehicle. Strip one end of
the hook-up wire and connect it to the brake
terminal of this socket.
4. Secure a single length of wire from the brake
connection of the socket to the underside of
the towing vehicle and route it to the engine
firewall. Position the wire to insure maximum
protection from scraping on the road surface
in rough terrain, flying stones, spray, etc. Also
avoid attaching wires near mufflers and
exhaust pipes. Wires should be clamped at
frequent intervals.
5. Remove a knock-out plug or cut a hole in the
firewall near the mounted controller.
Note: Solder or crimp clamp connections will
be required when connecting the controller
lead wires. Wrap electrician’s tape around all
bare wire joints. Do not use twist-type
connectors.
8. Making chassis ground connection is the next
installation step. Strip one end of the
remaining length of hook-up wire and connect
it securely to the ground terminal of the
socket at the rear of the towing vehicle.
9. Feed the wire under the towing vehicle to a
convenient chassis ground, such as a body
or chassis nut and bolt, battery ground post,
etc. Cut and strip the wire and attach it
securely to this ground.
A good ground connection
is essential for proper operation. It is the
responsibility of the installer to ensure a
good ground and that connections are
protected from the elements.
10. The power lead to the controller is last to be
connected. Strip one end of the hook-up wire
and feed it through a hole in the firewall from
the engine side. Solder or crimp this wire to
the remaining black controller lead.
Before proceeding, detach
one of the power cables from the towing
vehicle battery to prevent arcing.
Cut the hook-up wire to the proper length to
attach it to the live terminal of the starter
solenoid or relay, strip the wire and complete
the connection. Attaching this lead completes
your electrical connection. Reconnect the
towing vehicle battery cable.
6. Cut the wire to a proper length for reaching
the controller. Strip the wire and feed it
through the firewall hole.
7. Connect this wire to one of the lead wires
extending from the back of the controller.

Tape together wires leading from the
controller and secure them to the steering
column or underside of the dash. Plug all
holes in the firewall with sealant or rubber
grommets to prevent exhaust gases from
entering through the holes and to protect the
wires from abrasion.

Adjusting Your Controller
Controller knob adjustment – the pedal
mounted controller has a Trailer Brake Adjust knob
which affects the rate of application of the trailer
brake. This adjustment has no bearing on the
maximum braking capacity of the trailer brakes.
Because of the wide variety of towing vehicles and
trailers, it is necessary to balance the trailer brakes
with the towing vehicle brakes to provide for a safe,
comfortable stop. This adjustment should be made
to provide for a slight lead of the trailer brakes over
the tow vehicle brakes. Turning the handle
clockwise will decrease the rate of application of the
trailer brakes, while counter-clockwise will increase
the rate of application. When the desired setting is
reached, the controller will hold the adjustment but
may be varied at any time by rotating the knob as
described above. After this adjustment, there
should be no sensation of the trailer pushing the
tow vehicle during a stop, nor should there be an
excessive sensation of the trailer pulling the tow
vehicle during a stop.
