3. Verify the black wire has sufficient length to reach the ground point. If not, it can be extended by
splicing a 10-AWG wire to it. In this case, use approved wiring splicing methods and materials.
4. Strip the area of any paint or dirt to expose a bare metal surface, approximately ¾-inch square.
5. 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.
6. Cut the black wire to the required length plus some additional length for a service loop, then strip
insulation back approximately ¼-inch.
7. Crimp a ⅜-inch non-insulated ring terminal (supplied with the cable) to the end of the black wire.
8. Fully connect the radio’s DC Power Cable to the radio by mating its 3-pin connector to the radio’s
3-pin power connector as follows: Visually align the key and firmly push and turn the outer locking
ring clockwise until it stops. A click will be sensed to confirm proper mating.
9. 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.
10. 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.
Battery Ground WARNING: Before making connections to the battery’s positive
post, carefully disconnect the battery’s negative (ground) cable(s). This will
prevent tools or other metallic objects which come in contact with the battery’s
positive terminal from shorting to vehicle ground, causing sparks or even a fire or
an explosion! When disconnecting the negative cable(s), cover/insulate the positive
post(s) if it is not already so a tool cannot short between the posts. Some vehicles,
such as those with diesel engines have more than one battery; in this case,
disconnect the negative cables at all batteries.
Radio fuses should not be installed until all wiring is complete. This will prevent
the radio from powering up prematurely and/or causing an in-rush of current that
could lead to shorting of the battery, sparks, or even fire.
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 (one supplied with the bracket kit) 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.
