5. Install the supplied ring lugs onto the stripped end of the black lead, and onto the fuse
holder at the end of the red lead (see Figure 7).
6. Position the fuse holder as close as possible to the battery, ensuring that it is not close to
any hot engine component.
7. Mount the fuse holder, and dress wires as necessary. Connect the red lead plug adaptor
(on the fuse holder) to the matching receptacle on the red power cable.
8. Connect the black lead to the vehicle chassis ground. DO NOT connect the black lead
directly to the battery’s negative (–) terminal.
9. Remove the fuse from the fuse holder and connect the red lead of the power cable to the
positive (+) battery terminal. Verify that the adaptor cable is connected to the red lead of
the main power cable.
10. Plug the fuse into the fuse holder.
Cable Routing
• Before a wire is run or a hole is drilled, inspect the vehicle and determine how and where
you intend to mount the antenna, CPU Box and display.
• Plan wire and cable routing to provide maximum protection from overheating, battery
acid, moving parts and sharp edges.
• Keep cables away from ignition circuits to reduce noise pickup in the radio equipment.
• Verify that the cables are of sufficient length. Do not connect two short lengths with a
connector; doing so will result in signal loss. Refrain from loose excess in the cables, but
leave enough slack to allow reconnecting if necessary.
• Do not run cables externally or underneath floor mats.
Failure to mount the red lead of the power cable directly to the battery
may result in severe alternator whine interference.
