2. Prepare to connect the cable’s black wire to vehicle ground by locating an area of vehicle metal
within approximately two (2) feet of the radio. This surface must have a solid and stable connection
to vehicle ground. If not, add grounding strap(s) as necessary.
3. Strip the area of any paint or dirt to expose a bare metal surface, approximately ¾-inch square.
4. Drill a hole in the approximate center of the bare metal surface, and deburr it. A ⅜-inch non-insulated
ring terminal is supplied with the cable to make this ground connection. Therefore, hole diameter
should be appropriate for the utilized grounding screw/bolt size and type used to connect the ring
terminal to the bare metal surface. This hardware is not
supplied.
5. Cut the black wire to the required length plus some additional length for a service loop, then strip
insulation back approximately ¼-inch.
6. Crimp a ⅜-inch non-insulated ring terminal (supplied with the cable) to the end of the black wire.
7. Attach the ring terminal and black wire to the bare metal surface using stainless-steel self-locking
hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware to
ensure a reliable terminal-to-metal contact. Tighten securely.
8. Apply an approved paint or rust-inhibitor over the remaining exposed bare metal surface and around
the ring terminal.
7.2.2.2 Red Wire and Main Fuse Holder Connection (Radio’s Main Power Wire)
1. Continue installation of the radio’s DC Power Cable by routing its 20-foot 10-AWG red wire to the
location of the vehicle’s battery (or its main DC bus bar or stud). Remove interior panels, door kick
panels, etc., and route the wire through existing channels in the vehicle body as necessary. Protect the
wire from possible chafing where necessary. Tie and stow the wire as necessary.
Remote-Mount Radio — In a typical vehicle installation of a remote-mount radio, as a
time-
saving measure, the majority of the length of the Remote Control Cable between
the remote-mount radio and the control head can be simultaneously routed together with
the red and white wires of the radio’s DC Power Cable. Also, the Option Cable from the
back of the radio can also be simultaneously routed with most of the length of these two
wires and the Remote Control Cable. Detailed installation procedures for the Remote
Control Cable are included in Section 8.5 which begins on page 45.
Plan the routing of the 10-AWG red wire carefully, using an existing access hole in the
vehicle’s firewall if possible. Alternately, drill a new hole approximately ½-inch in
diameter and install a small rubber grommet (not supplied)
to protect the wire from
chafing at the hole’s sharp metal edge. To prevent fumes from entering the passenger
compartment, this hole/grommet/wire combination must also be sealed with a
silicon-based sealer before completing the installation.
Do not install any wiring or fuse holder over or in the near vicinity of the vehicle’s
engine. Excessive engine heat can cause permanent damage to these components and
can lead to intermittent electrical connection to the battery.
