Brake signal wire
to combined tow light harness
Step Three
Attach the brake signal wire
The brake signal wire is attached to the brake light
wire(s) in the towed vehicle’s electrical harness.
When the brake signal wire is connected to the 9700
(along with the other components of the braking sys-
tem), the 9700 will be activated when the towed ve-
hicle’s brake lights are activated.
Note: the brake signal wire is a six-foot length of
green wire, with a female bullet connector at one end.
1. Chose a convenient point on the towed vehicle’s
tow light harness to attach the brake signal wire, and
remove the protective loom covering that section of
the harness.
2a. If the towed vehicle has combined brake and
turn signal lights (Figure 2)…
• Cut the yellow wire (left turn/brake) on the har-
ness, and attach the ends with one of the supplied
yellow butt connectors (Figure 3). Repeat for the
green wire (right turn/brake).
• Then, run a small length of the supplied wire
from both butt connectors (Figure 3), and attach both
wires to the inputs of the included diode (Figure 3)
with two of the supplied spade connectors.
2b. If the towed vehicle has separate brake and turn
signal lights (Figure 2), the connection is the same
as above, except that only one wire (the brake light
wire) is attached to the diode…
• With a test light, determine which of the wires
in the tow light harness is the brake light wire — when
the test light is connected to the brake light wire, the
test light will illuminate when the motorhome’s brake
pedal is depressed.
• Cut the brake light wire, and connect the ends
with one of the included yellow butt connectors.
• Then, run a small length of the supplied wire
from the butt connector, and attach the wire to the
diode with another spade connector. Use either one
of the two inputs; leave the other input empty.
2c. If the towed vehicle has magnetic tow lights…
Note: additional connectors and, depending on the
application, additional wiring will be necessary to wire
a magnetic tow light system.
• Peel back a section of the protective covering near
the plug on the electrical cable — enough to use a test
light on the wiring and, later, to attach two butt connec-
tors. Then, using a test light, find the left and right com-
bined brake and turn signal wires.
• Cut one of the combined brake and turn signal
wires, and attach the ends with a butt connector. Run a
small length of wire from the butt connector, and attach
a female bullet connector to the end of the wire.
Attach a male bullet connector to another small
length of wire. Using one of the included spade con-
nectors, attach the other end of the wire to one of the
inputs on the diode.
Repeat for the other brake and turn signal wire.
Before towing, connect the male and female bullet
connectors.
• Trim the protective covering over the electrical
cable; wrap any exposed wiring with electrical tape.
• Connect to ground — at both vehicles, connect a
wire to any good chassis ground. Before towing, con-
