2014 - 2020 Chevy Tahoe:
This lightbar will mount
on both the driver and passenger side, on the
underside of the rear spoiler.
IMPORTANT! The
lightbar should be a minimum of 16" from any
radio antennas!
Preparing the Spoiler:
1. Each (half) lightbar fits between the outer end of
the spoiler and the curved indentation towards
the inside. Figure 1 shows where the lightbar sits
on the vehicle. Position the passenger side of the lightbar in the exact mounting location and clearly mark the two mounting hole locations
onto the spoiler. Repeat for the driver side of the vehicle, then (following factory specifications) remove the rear spoiler from the vehicle.
2. To locate where the wire holes are to be drilled refer to figures 1, 2 and 3. Figure 2 shows the spoiler with the plastic cover removed and
indicates the four wire hole locations. The location of the wire hole will be directly under the inside lighthead (Fig. 1).
Before removing the
cover
, drill two 7/16” wire holes through both the plastic cover and spoiler in the two locations labeled “A” in Figure 2.
3. Drill pilot holes for the four lightbar mounting holes you marked off in step 1 through both the plastic cover and spoiler using a 7/64 drill bit.
4. Remove the six screws holding the plastic cover to the spoiler and
remove the cover. As you remove the cover unplug the washer fluid
hose and 3rd brake light harness (Fig. 3).
5. Drill two 7/16” wire holes in the locations in figure 2 labeled “B” and run
both wire harnesses through as shown.
6. Extend the two lightbar harness cables toward the bottom of the spoiler following the brake light wire harness. They will follow the brake light
wire harness out of the spoiler. Leave just enough harness on the lightbar end, to plug into the lightbar.
7.
In the
plastic cover
you removed in step 4 slightly widen the lightbar mounting holes you drilled in step 3 so the cover will not catch on the
mounting screws when you install the lightbar.
IMPORTANT! Widen the mounting holes in the plastic cover only! DO NOT widen the
mounting holes in the spoiler itself or they will be too large for the mounting screws!
8. Run the two lightbar cables through the wire holes you drilled and through the waterproof boot (Fig. 3).
9. Plug the washer fluid hose and 3rd brake light harness back in and reinstall the interior trim.
10. Mount the rubber trim to each mounting bracket (where
the bracket touches the windshield - Fig. 4). Mount the
lightbar(s) to the spoiler with the supplied 6 X 1/2
Phillips Pan Head Sheet Metal Screws.
11. Reinstall the spoiler to the vehicle and make all
electrical connections. Attach the connectors to the
wire harnesses and make your connections. Wires
should follow the vehicle wire harness.
