connections inside the light bar are required.
NOTE: For electrical installation instructions, including instructions on mating and unmating the Quick
Disconnect connectors, refer to the Installation and Maintenance Instructions packed with the light bar.
Unpacking the Kit
After unpacking the kit, inspect it for damage that may have occurred in transit. If it has been damaged,
do not attempt to install or operate it. File a claim immediately with the carrier, stating the extent of the

Installing the Quick Disconnect
AIRBAG DEPLOYMENT: Do not install equipment or route wiring in the deployment of an airbag.
Failure to observe this warning will reduce the eectiveness of the airbag or potentially dislodge
the equipment, causing serious injury or death.
DRILLING PRECAUTIONS: Before drilling holes, check the area into which you plan to drill to
ensure that you do not damage vehicle components. All drilled holes should be deburred and all
sharp edges should be smoothed. All wires going through drilled holes should be protected by
a grommet or convolute/split-loom tubing.
NOTE: Due to the crown of the roof, the drainage of the roof seal is designed for installation of the
passenger side of the vehicle. The Quick Disconnect must be installed with the two electrical connectors
facing the rear of the vehicle.
IMPORTANT: Plan all cable routing before the installation.
Tools needed:
• Power drill
• 3/16-inch drill bit
• 7/8-inch drill bit
• Scratch awl
• RTV sealant

Preparing the Installation Surface
To prepare the installation surface for the stud plate:
1. Following the vehicle manufacturer instructions, remove the headliner.
2. From inside the vehicle, position the stud plate against the roof so it clears ribs, braces, and other
interferences. See Figure 1. For Ford Interceptor Utility, 2020+, verify that the seal will sit properly
between the roof ribs.

3. Mark the center of the large cable routing hole in the stud plate and drill a 7/8-inch hole.
4. Snap the appropriate roof seal into the 7/8-inch hole and use it as template to mark the three stud
locations with a scratch awl.
5. Remove the roof seal and drill the three holes with a 3/16-inch drill.

2. From outside the vehicle, route the cables through the roof seal, roof, and then the appropriate stud
plate.
3. Seal all drilled holes with RTV and snap the roof seal in place.
4. From inside the vehicle, push the stud plate into position. The friction of the roof seal will hold the
plate up.
5. Seal the cables to the roof seal with RTV and lower the housing over the studs.
6. Install the 8-32 stop nuts. Tighten the stop nuts just until the roof seal starts to bulge. Do not over-
tighten the nuts.
7. If you are not using the FPIU20 assembly, tighten the acorn nuts over the stop nuts. Do not
overtighten the nuts.
