14. Run the FM/DHF antenna cable from the antenna base mount to the cab entry point.
15. Tie-wrap the coaxial cable to the ground strap. At the tie-wrap holes in the antenna
base mount, place the FM/DHF antenna cable and ground wire into the split tube, and
tie-wrap them together. Be sure to include a service loop in the coaxial cable.
16. Run the cable(s) through the hole, and then place a 3/4" grommet around the cable(s)
and into the hole. Near the point where the cables are entering the truck body, fasten
the coaxial cable to the ground strap with a tie wrap.
Note: Use the grommet most appropriate for the wall
thickness; the installation kit comes with two grommet sizes
for either a 1/16" or a 1/8" wall thickness.
17. Place cables in the path that they will follow from the base mount to the entry hole.
Join the GPS cable near the antenna-mounting bracket so that all cables can be placed
in the same split tubing. Measure the required length and cut the split tubing. Place
the cables in the split tubing. At the place where the coax cable and the ground strap
are tie-wrapped together near the cab entry point, the ground strap should exit the
split tubing. Secure the ground strap exit point with tie wraps.
18. Secure the split tubing, with cables running through it, to the truck cab body with tie
wraps. Use tie-wrap bases on the truck cab body. Be sure the first and last tie-wrap
base plates are also screwed to the cab body. Additionally, service loops should have
tie-wrap base plates screwed on at the beginning and end of the service loop.
