Wiring the Legend in the Vehicle

Wiring the Stop/Turn/Tail Lights

The light bar's stop/turn/tail lights are a factory-configured option. The light bar is
shipped with the option's three-conductor cable ready for splicing into the vehicle
harness. For the location of the lights, see Figure 3 on page 25.
QUALIFICATIONS: To properly connect a stop/tail/turn light, you must have
a good understanding of automotive mechanical and electrical procedures
and systems along with proficiency in the installation and service of safety
warning equipment. Always refer to the vehicle's service manuals when
performing equipment installations on a vehicle.
BATTERY EXPLOSION: To avoid a battery explosion, always disconnect
the negative battery cable first and reconnect it last. Avoid causing a spark
when connecting near or to the battery. The gases produced by a battery
can cause a battery explosion that could result in vehicle damage and
serious injury.
After mounting and wiring the light bar to the vehicle, follow these steps to wire the
light bar's stop/turn/tail lights:
1. Disconnect the vehicle battery's negative ground cable, and then the positive
cable.
2. Locate the three-conductor cable exiting the light bar with red, black, and green
wires.
NOTE: If installing the option in a vehicle that has its turn signal lights separate
from its brake lights, you must purchase a tail light converter.
3. Splice the appropriate cables into the vehicle's wiring. See Figure 10. The input
leads require a positive (+) 12 Vdc signal to activate.
4. Reconnect the battery's positive terminal, and then the negative terminal.
5. Test to verify that the light bar's stop/turn/tail lights turn on and off with the
vehicle's stop/turn/tail lights.
