BURN HAZARD: After prolonged operation, the Latitude dissipates heat and can cause burns. Do not
hold it in your hands for extended periods of time. Do not touch it during, or shortly after, operation.
Always allow the stick light to cool before handling.
To wire the control head to power:
1. Route installer-supplied red and black 18 AWG (minimum) wires to the power source. Ensure that the power
source is capable of supplying an additional 10 amperes.
2. Connect the black wire to a known good chassis ground. This connection must be capable of supplying
10 amperes. Do not connect the red wire to the positive (+) power source terminal at this time.
3. Wrap the control cable’s stripped wire ends with tape and route the cable to the mounting location of the
control head.
4. Crimp four 1/4-inch straight-terminals on the ends of the cable wires and the jumper wire combination. See
Figure 3.
5. Connect the terminals on the switch as shown in Figure 3.

HIGH CURRENT ARCING: Do not connect this system to the vehicle battery until ALL other electrical
connections are made, mounting of all components is finished, and you have verified that no shorts
exist. High current conductors can cause hazardous sparks or burning wire, resulting in electrical
fires.
PCB DAMAGE/IMPROPER WIRING: 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.
To wire the illuminated ON/OFF switch:
1. Connect the right-angle terminal on the ground lead of the switch bracket to the gold terminal (Pin 3) of the
ON/OFF switch. See Figure 3.
