In any application, trim and strip wires. Crimp on ring lug for battery connections. For ignition switch connections, crimp
on ring or spade lug (whichever is required).
Note: In cases where alternator whine or interference is a problem, isolate the green lead with a relay (Motorola Part No.
5900813674) (see Figure 13).

If either wire is to be connected in the vehicle's battery compartment, pass
the end of the wire through the same firewall hole that the red radio power
cable uses. At this point, install a fuseholder assembly in both wires
(shown in Figure 14); the following procedures apply to both green and
orange wires:
•
A fuse will need to be placed in-line for both the orange and green
wires; consideration should be taken when deciding where to place
the fuses so that they are easy to inspect. However, they should also
be placed as close as possible to the battery or the vehicle's ignition
switch terminal.
•
After choosing the fuse locations, the fuse receptacles need to be
installed. This is done by cutting the wire at the chosen location and
stripping 1/8-inch of insulation on all loose ends. Make sure the wire
will reach its intended destination.
•
On the end still connected to the cable kit, slide the plastic insulator
fuseholder over the wire as shown in Figure 9. Insert the stripped end
of that wire into one of the metal fuse clips, and crimp it closed onto
the exposed wire. Solder it for a better electrical contact.
•
On the end of the loose wire, repeat the above crimping and soldering
process with the remaining metal fuse clip.
