Installation Procedure 5
5. For proper seating of the bushing assembly and locking nut, remove any burrs and/or foreign
matter from above and below the (top) 3/4-inch mounting hole. This should be done for at
least 1/8 inch out from the hole edge. For double-roof construction vehicles (without dome
light), also be sure to clear the second (or bottom) 3/4-inch hole of any burrs.
6. Determine the routing of the cable from the antenna bushing assembly to the radio set, and
then remove the molding and trim necessary to facilitate pulling the cable through.
NOTE: To ensure ease of assembly, thread the locking nut on the end of the bushing assembly
a few times before installing. This removes any burrs that might be present.
7. Insert the end of the coaxial cable into the mounting hole, and then route the cable between
the roof and headlining to the radio.
NOTE: If you experience difficulty with cable routing, use an electrician's fishtape to perform
this step.
8. Refer to Figure 2 on page 5 . Apply a generous amount of silicone grease (supplied) to the
inner and outer threads of the locking nut. In addition, be sure to apply some silicone grease
to the rubber "O" ring washer and the groove in the locking nut in which the “O” ring washer is
seated.

When installing the lead-in cable, the cable should not be
shortened.
