Trailer Tow Wiring - Information
NO: 08-03-94
GROUP: Electrical
DATE: Jan. 28, 1994
SUBJECT:
Trailer Tow Wiring
MODELS:
1993 - 1994 (ZJ) Grand Cherokee/Grand Wagoneer
DISCUSSION:
Connecting trailer lights directly to the body harness at the rear of the vehicle can cause damage to the lamp outage module. The lamp outage module is
designed to handle a 5 amp current load. This is adequate for the operation of the vehicles lighting system. When additional lights are added to the
system such as trailer lights, the 5 amp limit can be exceeded. This can cause a failure of the lamp outage module.
If trailer towing is required and the vehicle is not equipped with a trailer tow package, the MOPAR accessory trailer towing harnesses are the only
approved method to provide for trailer lights. These harnesses are designed to provide current to the trailer lights, but bypass the lamp outage module.
