RUNNING CABLES

To assure the feasibility of the planned cable routings. it is suggested that the
cables be run before mounting the radio. Be sure to leave some slack in each cable
going to the radio so that the radio may be pulled out for servicing with the power
applied and antenna attached.
Try to route the cables away from locations where they will be exposed to heat
(exhaust pipes, mufflers, tailpipes. etc.). battery acid, sharp edges, or mechanical
damage or where they will be a nuisance to automobile mechanics. the driver, or
passengers. Keep wiring away from electronic computer modules. other electronic
modules and ignition circuits to help prevent interference to these components and
radio equipment.
In addition. try to utilize existing holes in the fire wall and trunk wall and the
channels above or beneath the doors. Also, channels through door and window
columns that are convenient for running cables may be used, unless planning to
install rigid or flexible conduit in which to run the cables.
Power And Ignition Cable
The power cable consists of a red lead, an orange lead, a black lead, a 3 pin
systems plug. and a set of fuses and fuse holders to be installed as indicated in Figure
3.
To install the power cable, drill a 5/8 inch hole in the firewall for the cable run
and insert the rubber grommet. Starting with the plug end of the cable at the location
of the radio, run the three cable leads through the hole. Secure the cable at several
locations within the engine compartment.
To install the fuses:
1. Cut off 12 to 18 inches from the red and orange wires.
2. Strip back the insulation approximately 3/8 of an inch on each end of the wires.
3. Lubricate the wire tips with liquid soap to insert the wires into the fuse holders.
Pull the wire ends through the small opening at the end of each fuse holder
section and crimp a fuse connector to each wire.
