Step 2 – Install new grille brackets
Loosely install your new grille brackets, using the OEM T40 bolts and T40 bit.

Assemble your SS5 lightbar using the CrossLink lightbar instructions.
Step 4 – Mount CrossLink

Wiring Instructions
The following instructions are for Ford Broncos with an Auxiliary Switch Bank. If you do not have the Auxiliary Switch Bank, use the included toggle switch adapter wire to route a switch. All power sources must be fused.

Step 5 – Connect main beam wire
Locate the auxiliary switch wiring above the grille. Access the owner’s manual in the head unit and determine what wire color you will connect to based on the amperage rating. Connect the yellow wire for the main beam to an auxiliary switch wire. Using wire strippers, remove enough insulation to make a good connection. Insert the wire into the butt connector and crimp it to secure the connection.
Step 6 – Connect backlight wire
Repeat this process for the blue backlight wire. The wire for the backlight can be connected to any of the other auxiliary switch wiring locations, like the back of the hood, or if you have a Stage Series backlit light already installed, you may choose to tap it into the same switch.
Step 7 – Connect battery terminals
Connect positive and negative battery wires to the battery, or to main power terminals near the fuse box.
Step 8 – Finalize wiring
Secure the wires, test thoroughly, and tighten all hardware to complete your installation.
IMPORTANT: All power sources must be properly fused.
SS5 Backlight Programming & Resync Instructions
SS5 Backlit lights include programmable RGB backlighting.
To Change Backlight Color:
Cycle the backlight power off and on to advance to the next color mode.
To Resynchronize Multiple SS5 Units:
- Turn the backlights on.
- Cycle through all available colors and modes.
- Complete three full color cycles.
- Leave the lights on the desired color.
Running three full cycles forces all SS5 backlights into the same programming state.
