Installation Instructions
MOUNT ON EITHER SIDE
Introduction
MOUNTING HOLES
Mounting Under Instrument Panel
The Warner Electric manually operated Utility
Controller operates 4, 6, or 8 twelve-volt electric
wheel brakes. Some of the features of this
control are:
• Highly sensitive for accurate brake control
• Rated at 30 amperes
• Manually operated
Installation Instructions
These instructions provide for ease of
installation. Please follow them carefully. The
basic installation steps are:
1. Mount the controller inside the towing
vehicle.
2. Connect the controller electrically.
Failure to follow these
instructions may result in product
damage, equipment damage, and serious
or fatal injury to personnel.
1. Position the controller under the instrument
panel to the left or right of the steering
column, based on available space and driver
preference.
2. While sitting in a normal driving position,
place the controller so its handle is within
easy reach.
3. Remove the controller cover and, while
holding the controller in place, select at least
two holes through the case which best mount
the controller. Mark the underside of the
instrument panel through these holes.
4. Drill 3/16" diameter holes where marked,
being careful not to damage anything under
the instrument panel.
5. Attach the controller with 3/16" bolts, nuts
and lockwashers, and tighten securely. Bolt
heads are to be inside the controller.

1. Electrical connection is required for all
installations. Approximately 25 ft. of
automotive-type multistranded 12 gauge
or heavier single wire with tough,
thermoplastic insulation meeting SAE
standard J558a is required. Note: When
towing a trailer which will carry variable
loads, or which is light weight when
compared with its brake capacity, a
Warner Electric Load Control, Part No.
1300-78, may be required to properly
proportion braking force between the
trailer and the towing vehicle. See Optional
Equipment, page 4.
2. 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.
3. Secure a single length of wire from the
brake connection of the socket to the underside of the towing vehicle and lead 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.
4. Remove a knock-out plug or cut a hole in
the firewall near the mounted controller.
5. Cut the wire to a proper length for reaching
the controller. Strip the wire and feed it
through the firewall hole.
6. Connect this wire to the blue brake lead wire
extending from the back of the
controller.
Note: Solder or crimp clamp connections
will be required when connecting all three
controller lead wires. Wrap electrician’s
tape around all bare wire joints. Do NOT
use twist-type connectors.
7. Making a 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.

8. 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.
9. Two Utility Controller leads are still to be
connected. The red lead actuates the
stoplights when the controller is operated
manually. An interrupted stoplight circuit for
turn signals is used on most towing
vehicles. Connect the controller’s red lead
to the output side of the towing vehicle
stoplight switch. (This switch could be a
pressure switch in the brake line or a limit
switch activated by the brake pedal.)
Connect an inline fuse in series between the
red lead and the stoplight switch. This fuse
should be the same type and rating as
recommended for the tow vehicle’s existing
stoplight circuit. Splice a short length of
hook-up wire to the red lead to reach the
stoplight switch output. If your towing
vehicle has some other system, consult your
automotive dealer.
13. 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.
Optional Equipment
When the trailer load is variable or less than
trailer bake capacity, a Warner Electric Load
Control, Part No. 1300-78 should be added in
series with the brake circuit. The Load Control
provides the capability to properly proportion
the braking power of the trailer brakes to the
trailer weight. The Load Control is connected
into the trailer brake wire connected to the blue
lead from the controller. Its position is shown
in the wiring diagram under the “Electrical
Connection”. The illustration shows the
simplicity of adjusting this resistor to increase
or decrease trailer brake torque. Contact your
Warner Electric distributor or the factory if you
require additional information.
10. The black or power lead of the controller is
last to be connected. Enough hook-up wire
should remain to make this connection. Strip
one end of this hook-up wire and feed it
through a hole in the firewall from the engine
side. Solder or crimp clamp this wire to the
black controller lead.
11. Detach one of the power cables from the
towing vehicle battery to prevent arcing.
12. 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.
Re-connect the towing vehicle battery cable.
