1. Decide the best location for the cables to enter the
vehicle, and the location of the switch and receiver
(see “Installing the switch and receiver” below.) Drill
a 1/2” hole in the roof, push wires inside. Make
proper connections (remember you must have fil-
tered +12 VDC power source).
2. Place cable-entry plate over hole and cables. Screw
in place. Seal plate and screw holes with approved
sealant (not included).

3. Depending on the length of the cable on the roof,
you may need to use cable clamps or wire ties (not
provided) between the unit and your cable-entry plate.
Clamping the cable every 12”-16” should eliminate
any unnecessary cable movement, Figure 7.
