& CABLE ROUTING
STEPS:
1 - When location has been well determined, fasten the antenna
tuning box with 3 self-tapping screws, to the vehicle frame.
2 - Clean internal bumper surface with degreaser solvent before
fixing (sticking as vertically as possible) the antenna.
3 - Route the input cable through the engine compartment
(secured with tie-wraps), through firewall and into the vehicle
to the radio, keeping them away from any moving parts.
4 - After routing cables, attach loose connectors,
supplied with the antennas.
NOTE:
- Do not connect the cable to the radio until
the tuning procedure is complete!
