DRILLING PRECAUTIONS: When drilling holes, check the area into which you are drilling to
ensure that you do not damage vehicle components. All drilled holes should be deburred and all
sharp edges should be smoothed. All wire routing going through drilled holes should be pro-
tected by a grommet or convolute/split-loom weaving.
3.
Drill a hole sized for the installer-provided hardware to be used in step 4 at each drill position mark.
4.
Secure the mounting bracket to the mounting surface with two installer-supplied, thread-forming,
1/4-inch screws or other hardware appropriate for the installation.
5.
Before fastening the controller to the bracket, continue with the electrical connections as described
in the next sections.

Connecting Power to the Controller
HIGH-CURRENT ARCING: Do not connect this system to the vehicle battery until all other elec-
trical connections are completed and you have verified that no shorts exist. High current shorts
can cause hazardous sparks or burning wire, resulting in an electrical fire.
The controller is equipped with a nine-position terminal block and an insulated spade connector.
Installer-supplied red and black wires of the proper gauge for the current and run length of the specific
installation are also required. For the recommended wire gauge, see Table 5 on page 5. The ground
wire should be sized to handle the total current used by the light bar and controller. Connect the light bar
using a red wire of the appropriate gauge to a fused positive power source. Installer-supplied 18 AWG
(minimum) red wire is required for the connection of the controller to the positive power source.
To make the power connections to the controller:
1.
Strip 1/4 inch of insulation from the main ground wire and crimp the proper spade connector onto it.
