Wiring: Connecting Wires to the Battery
WARNING! If you are supplying your own wiring that connects to the positive or negative terminal of the battery, fuse sizes must be sized accord-
ing to STLs provided fuse to be considered fused properly to the battery in order to carry the load.
Route the power cables by opening the wiring shield and running the cables through it towards your vehicles rewall.
Follow the factory wiring harness through the rewall.
If it is necessary to drill a hole in the rewall for the power cables, be sure no components will be damaged from drilling. As with all holes
that are drilled, le the edges down smooth and insert a grommet to protect the cables.
Route the cable along the factory wiring harness towards the battery.
Wire your power cables (Red with In Line Fuse (STL Supplied) and Black cable) to your battery to power up your Light Bar.
You will want to ensure your grounding cable is taken directly to the negative terminal of your battery to avoid any electrical feedback
which may disrupt your Light Bar system.
DO NOT allow the positive (Red wire) and negative (Black wire) to touch one another. This may cause injury to you and damage your equip-
ment by causing a short in the unit that is not covered under the STL warranty.
Wiring: Connecting Wires to Control Box
This unit will feature a power harness with three (3) colored leads with a connector that plugs into the Cig Plug. When not utilizing the Cig
Plug reference the Wiring Diagram above.
Now that you have pulled the cable into the vehicle attach the connector back to your Light Bar’s wire harness in the CORRECT positions
using a pin pusher and plug it into your Cigarette Lighter Plug. If you do not know the correct position of each wire in the connector call
customer service at 800-757-2581 before proceeding.
If you did not purchase the Cig Plug and are using your own switch box , wire the cables accordingly into your control panel by referencing
the wiring diagram and instruction manual of your control panel.
