Trailer Connector: Description and Operation
Trailer Tow Wiring - Operation
OPERATION
If an aftermarket electric trailer brake controller is used, the electric brake kit available through MOPAR(R) includes a pigtail wire harness and
instruction card to make installation easier. The connection (4-way connector) for the harness is located under the instrument panel to the left of the
steering column near the top of the large body harness connector bracket. Refer to the appropriate wiring information.
The battery line of this pigtail harness may be used to charge the trailer battery. However, a battery isolation unit is not supplied and the trailer battery
may discharge the vehicle battery when the engine is not running. The battery line is protected by a fuse or a circuit breaker.
The trailer tow wiring circuits and connections may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring
information.
