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 connectorcontains 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.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.Your vehicle has a simple ignition key actuated test
which you can use prior to going to the test station. To
check if your vehicle’s OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.

2. Use specified fuses only.
3. Always properly reinstall the cover.
VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
•Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Fuse and Relay Center, located in the
engine compartment. The I.O.D. cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
•The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
•As an alternative to the above steps you may, discon-
nect the negative cables from both batteries.
