c.
Route user-supplied red and black
14-gauge wires through the firewall and toward the
battery. Connect the red wire to one end of the
supplied 25-ampere circuit breaker (Part No. 152118-
25). Do not connect the other end of the circuit
breaker to the (+) positive terminal until ALL wiring
is complete.
d.
Strip 1/4" of insulation off each
wire at the eleven-position connector end. Insert the
eight 22-gauge wires, the 16-gauge red wire, and the
14-gauge red and black wires into the connector as
shown in figures 3-11 and 3-12. Tighten the screw at

NOTE
Although output #3 is rated at 40-amperes,
the circuit is protected by two 20-ampere
fuses which are connected in parallel. TB1-3
(output #3) has two terminals in parallel to
obtain that rating.
6.
When the current requirement for
LIGHTS 3 exceeds 30-amperes, split the load be-
tween the two terminals of TB1-3 or connect the two
terminals together with the supplied jumper (Federal
Part No. 233A198 or equivalent).
CAUTION
Personal injury, vehicle component damage,
and/or damage to the Amplifier Unit
will occur if the LIGHTS 3 terminal (TB1-3)
is shorted to the chassis. Before replacing the
chassis cover, ensure that the jumper (if in-
stalled) between the two terminals of TB1-3
will not short to the chassis.
7.
Replace the chassis cover. Slide it
forward and secure with the two screws.
C.
SignalMaster Connections.
The Amplifier unit is not supplied with a
fuse installed for the SignalMaster. The kit contains
a 25-ampere and a 7.5-ampere fuse. Follow the
appropriate installation instructions depending on
the type of SignalMaster, halogen or LED.
1.
Halogen.
a.
Unless previously routed, route
the SignalMaster cable toward the Amplifier Unit.
Use caution to avoid scraping the wires on any sharp
edges.
b.
Cut the cable to the appropriate
length as required.
