DC Power Cable Installation
4. Connect the black lead of the power cable to the nearest vehicle chassis ground point (using
the provided ring lug if necessary). Shorten the black lead to remove any excess cable.
(See Figure 1-2 Power Cable Assembly.)
NOTE Locate a good vehicle ground point. The vehicle frame provides the best ground. Optimum
radio performance can only be achieved with a very low resistance ground connection.
Verify that the connections between the battery negative terminal, vehicle chassis, and
engine block have low resistance.

5. Place the fuse holder close to the battery. Ensure that it is not near any hot engine
component. Mount the fuse holder using its mounting hole and dress the wires as required.
6. Insert the stripped end of the red lead of the fuse holder into the ring lug hole and crimp it.
Connect the fuse holder red adapter lead plug to the mating receptacle on the red lead of the
power cable. (See Figure 1-2 Power Cable Assembly.)
7. Connect the power cable black lead directly to the vehicle chassis ground.
8. Connect the red lead ring lug from the fuse holder to the positive (+) battery terminal. Make
sure the adapter cable is connected to the main power cable red lead.
NOTE Failure to mount the red lead of the power cable kit directly to the battery may result in
severe alternator whine interference.
Carefully check that all connections are proper. Insert the fuse into the fuse holder and close the
cover. (See Figure 1-2 Power Cable Assembly).
