SUBJECT:
CELLULAR TELEPHONE INSTALLATION GUIDELINES
MODELS AFFECTED: 1981-1985 CADILLACS WITH DIGITAL FUEL INJECTION
The following are general guidelines for installing the new cellular telephones available in some areas, into Cadillac vehicles equipped with Digital Fuel
Injection. These guidelines are provided so that dealers can communicate this information to local mobile telephone installers when necessary. It is not
Cadillac's recommendation that dealers attempt modifications of currently installed phones, but rather that this information be used by mobile phone
installers when installing or diagnosing their system in Cadillac vehicles.
1.
Transmitter location:
Locate the transmitter in the trunk, preferably to one side as convenient.
2.
Antenna location:
The antenna should be either the permanent mount type located in the center of the rear deck lid and having an effective ground connection or the
new design glass mount attached to the rear window.
3.
Wiring:
The connections required for most radio telephone installations are:
A.
battery and ground for the transmitter, B. battery for the handset, C. the antenna lead-in, D. a multiconductor signal cable between the
handset and the transmitter.
E.
To prevent possible damage to the system and wiring, the power connections should be fuse protected. Most available systems provide this
protection in the wiring.
Some installations are made with a tie to ignition as a signal only (as opposed to a power feed).
A.
Connection Locations:
1.
Battery, ground, handset battery:
The positive battery connection should be made to the battery junction block. The power feed should be #16 AWG wire or larger.
The negative connection should be made at the negative battery cable jumper lead ground connection. Neither connection should be
made at the battery cable to battery connection.
2.
Ignition:
When requiring the ignition signal (as opposed to a Power Feed), use the ignition 3 circuit with a terminal so labeled on the left
under dash fuse block. A sketch of fuse block is located in the Owner's Manual.
B.
Line Routing:
The power leads should be brought through the RH grommet and run through the conduit under the RH door sills, under the rear seat, and
into the trunk through the rear bulkhead. Attempt to maintain distance between the power leads and sensitive electronics (pressure sensors
and Electronic Control Module/Body Computer Module) located in the right side of the dash.
