STEP 3 – INSTALL CABLES
To ensure the feasibility of the planned cable routings, it is recommended that
the cables be run before mounting the radio. The radio can be installed as a
Front Mount, Remote Mount or Cassette Mount. The type of mount, the
application, and the options to be installed should be considered when
planning the cable runs. The following figures should be referenced
throughout the installation:
•
Front Mount Installation Diagram - Figure 8 thru Figure 12
•
Front Mount Cable Diagrams - Figure 13 thru Figure 17
•
Remote Mount Installation Diagrams – Figure 18 thru Figure 24
•
Remote Mount Cable Diagrams – Figure 25 thru Figure 29
Be sure to leave some slack in each cable going to the radio, so the radio can
be pulled out for servicing with the power applied and antenna attached. Coil
any surplus cables and secure them out of the way. 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. In order to prevent interference, keep wiring away from
electronic computer modules, other electronic modules, and ignition circuits.
In addition, try to utilize existing holes in the firewall, trunk wall, and the
channels above or beneath doors. Channels through door and window
columns, convenient for running cables, can also be used unless rigid or
flexible conduit is to be installed for cable runs.
Power Cable
The USA power cable (19B802622P1 or P3) consists of a red lead (A+) and a
black lead (A-) connected to a molded 2-pin power connector and supplied
with ring terminals. The EURO power cable also consists of a red lead (A+) a
black lead (A-) terminated with ring terminals, but it is connected to P1 of the
accessory cable or P1 of the control cable (in remote applications).
To install the power cable:
1. Drill a 5/8
”
hole in the firewall for the cable run and insert the rubber
grommet. Run the cable through this grommet to the battery location.
Secure the cable at several locations within the engine compartment to
prevent possible damage to cable.
2. Strip back the insulation approximately 3/8
″
from the end of the black
lead. Slide one of the large heat shrink sleeves onto the wire and crimp a
battery ring terminal onto this lead. Heat shrink the sleeve over the crimp
connection. Connect the black lead directly to the battery negative (-) or
ground frame member.
