Connecting Trailer Lighting And Electric Trailer
Brakes
NOTE: A 4-way trailer tow connector, located behind
the bumper, is standard equipment on all Ram pickup
models. This connector contains the following vehicle
circuits: park/tail lamps, left stop/turn lamp, right stop/
turn lamp, and ground. With the optional Trailer Tow
Prep package a 7-way connector is also provided with the
following additional circuits: backup lamp, trailer battery
and electric brake.
NOTE: There is also a 4–way connector located under
the instrument panel, located to the left of the brake
pedal that is used for the electric brake. This connector
contains the following vehicle circuits; power ground,
battery, stop lamp switch and electric brake feed. The
4–way is optional with the trailer tow prep package.
CAUTION!
Adding lights or electrical devices to the headlamp/
park lamp circuit can be accomplished by connecting
to the standard 4-way trailer tow connector located
behind the rear bumper. The maximum current ca-
pacity for the park lamp circuit should not exceed 15
amps total (a typical park lamp bulb can draw from
0.5 to 1.0 amperes of current).
No connections can be made to the headlamp switch
itself, because it is not designed for high current
applications. Connections to the headlamp switch
will cause the exterior lights to malfunction.
