NOTE
When selecting a mounting location for the control head,
it is necessary to keep in mind the SignalMaster’s cable
length. Plan wiring and cable routing before installation.
1.
Select a mounting location for the control head that
allows the vehicle and controls to be operated safely at all times.
2.
Use the control head as a template and scribe two
drill position marks at the selected mounting location.
CAUTION
Before drilling holes in ANY part of a vehicle, be sure
that both sides of the mounting surface are clear of parts
that could be damaged; such as brake lines, fuel lines,
electrical wiring or other vital parts.
3.
Drill two holes at the previously scribed position
marks.
4.
Secure the control head to the mounting surface
with two user-supplied sheet metal screws.
C.
Electrical Connections.
WARNING
Failure to observe this WARNING may result in fire,
burns or blindness.
If shorted to vehicle frame, high current conductors can
cause hazardous sparks resulting in electrical fires or
molten metal.
If additional cable length is required, splice the same
gauge (or heavier) wire to the leads.
DO NOT connect this system to vehicle battery until ALL
other electrical connections are made and mounting of all
components is complete.
Verify that no short circuits exist, before connecting to
the Positive (+) battery terminal.
1.
Power Connections.
a.
Route the red and black 14-gauge wires to the
power source. Ensure that the power source is capable of supplying
an additional 25-amperes.
b.
Connect the black wire to a known good chassis
ground. This connection must be capable of supplying 25-amperes.
c.
Do not connect the red wire to the positive (+)
power source terminal at this time.
2.
Control Head Connections.
a.
Wrap the control cable’s stripped wire ends
with tape and route the cable to the control head mounting
location.
b.
See figure 2. Crimp five 1/4" straight terminals
on the cable wire ends and jumper wire combination.
c.
Connect the terminals on the switch as shown
in figure 2.
3.
Illuminated Power Switch.
CAUTION
Improper wiring of the illuminated switch feature will
result in printed circuit board damage. Ensure that the
chassis ground lead is connected to the gold (pin #3)
terminal and that the unterminated end of the lead is
connected to a known good chassis ground.
a.
See figure 2. Connect the right angle terminal
on the switch bracket ground lead to the gold (pin #3) terminal of
the on-off switch.
b.
Route the unterminated end of the ground lead
to a known good chassis ground. Cut the lead to length and crimp
the supplied ring terminal on the lead.
NOTE
If necessary, additional 18-gauge wire may be spliced to
the ground lead.
c.
Secure the lead to the chassis ground with a
user-supplied screw.
4.
Low Power Warn Connections.
a.
Connect one end of a user-supplied 22 gauge
wire to the vehicle parking brake switch so that + battery voltage
is supplied when the vehicle ignition switch is on and the parking
brake is applied.
NOTE: TWO WIRES ARE
CRIMPED IN ONE TERMINAL
