2005 DODGE RAM 1500 GAS wiring

•The driver and front passenger seats should be moved
back as far as practical to allow the airbag room to inflate.
WARNING!
•Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won’t deploy at all.
Always wear your seat belts even though you
have airbags.
•Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
•If the vehicle has window airbags, they also need
room to inflate. Do not lean against the door or
window. Sit upright in the center of the seat.
Airbag System Components
The airbag system consists of the following:
•Airbag Control Module
•AIRBAG Readiness Light
•Driver Airbag
•Passenger Airbag
•Steering Wheel and Column
•Instrument Panel
•Crash Sensor
•Interconnecting Wiring
•Knee Impact Bolsters
•Passenger Side Frontal Airbag ON/OFF Switch (Stan-

48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The Window Airbag System, on vehicles equipped,
consists of the following:
•AIRBAG Readiness Light (shared with the front airbag
system)
•Window Bags Above the Side Windows.
•Airbag Control Module (shared with the front airbag
system)
•Side impact sensors
•Interconnecting Wiring
How The Airbag System Works
•
The airbag control module determines if a frontal
collision is severe enough to require the airbags to
inflate.
•The airbag control module will not detect roll over, or
rear collisions.
•The airbag control module also monitors the readiness
of the electronic parts of the system whenever the
ignition switch is in the START or RUN positions.
These include all of the items listed above except the
knee bolsters, the instrument panel, and the steering
wheel and column. If the key is in theOffposition, in
the ACC position or not in the ignition, the airbags are
not on and will not inflate
•The airbag control module also turns on the AIR BAG
light in the instrument panel for 6 to 8 seconds when
the ignition is first turned on, then turns the light off.
•If it detects a malfunction in any part of the
system, it turns on the light either momen-
tarily or continuously. The instrument cluster
will flash the seat belt indicator if it detects a fault with
the airbag indicator.

Maintaining Your Airbag Systems
WARNING!
•Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured because the airbags are not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or
the upper right side of the instrument panel. Do
not modify the front bumper, vehicle body struc-
ture, or frame.
•You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolster.
•It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has airbags.
Airbag Light
You will want to have the airbags ready to inflate for your
protection in an impact. While the airbag system is
designed to be maintenance free, if any of the following
occurs, have an authorized dealer service the system
promptly:
•The airbag light does not come on or flickers during
the 6 to 8 seconds when the ignition switch is first
turned on.
•The light remains on or flickers after the 6 to 8 second
interval.
•The light flickers or comes on and remains on while
driving.

Headlamp Delay — If Equipped
To aid in your exit, your vehicle, if equipped, can be
programmed by your dealer with a headlamp delay that
will leave the headlamps on for 0, 30, 60, or 90 seconds.
This delay is initiated when the ignition is turned OFF
while the headlamp switch is on, and then the headlamp
switch is cycled off. The headlamps will remain on for 60
seconds. Headlamp delay can be cancelled by either
turning the headlamp switch ON then OFF or by turning
the ignition ON.
Headlights, Parking Lights, Panel Lights
When the headlight switch is rotated to the first
position, the parking lights, taillights, side marker
lights, license plate light and instrument panel
lights are all turned on. Rotating the headlight switch to
the first position will also turn on the cab top clearance
lights, flare lights, and tailgate lights if the vehicle is
equipped with these lights. The headlights will turn ON
when the switch is rotated to the second position. TheLAMP OUTindicator will be illuminated in the instru-
ment cluster if a defective bulb or wiring circuit is
detected for the headlamp system.
Your vehicle is equipped with plastic headlight lenses
that are lighter and less susceptible to stone breakage
than glass headlights.

CARGO LIGHT
The cargo lights are turned on by rotating the dimmer
control to the optional fully upward position. The cargo
lights will also turn on for 30 seconds when a key fob
Unlock is pressed, as part of the illuminated entry
feature.
MULTIFUNCTION CONTROL LEVER
The multifunction control lever is located on the left side
of the steering column.
Turn Signals
Move the lever up or down to signal a right-hand or
left-hand turn.
The arrow on either side of the instrument cluster flashes
to indicate the direction of the turn, and proper operation
of the front and rear turn signal lights. If a defective bulb
or wiring circuit is detected for the turn signal system, the
arrow indicators will flash at a faster rate. Also, the
LAMP OUTindicator in the instrument cluster will beilluminated and a chime will be heard. If an indicator
fails to light when the lever is moved, it would suggest
that the switch or indicator lamp is defective.
You can signal a lane change by moving the lever
partially up or down.

20. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
If the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.
The trip odometer shows individual trip mileage. To
toggle between the odometer and the trip odometer,
press the Odometer/Trip Odometer Button. To reset the
Trip Odometer, press and hold the button while in trip
mode, until the Trip Odometer resets.
NOTE:There is also an engine hour function. This
indicates the number of hours the engine has been
running. To display the engine hours perform the follow-
ing: Place the ignition in RUN, but do not start the
engine. With the odometer value displayed, hold the trip
button down for a period of 6 seconds. The odometer willchange to trip value first, then it will display the engine
hour value. The engine hours will be displayed for a
period of 30 seconds until the ignition is turned off or the
engine is started.
21. TOW/HAUL (Automatic Transmissions Only)
The TOW/HAUL button is located at the end of the gear
shift lever. This light will illuminate when the TOW/
HAUL button has been selected. (See page 236 for more
information.)
22. LAMP OUT Light
The LAMP OUT indicator in the instrument cluster alerts
the driver if a defective bulb or wiring circuit is detected
for most of the exterior lamps - headlamps, turn signal
lamps, and stop lamps.

Axle Lubricant and Trailer Towing
1500 Models
•
1500 Modelrear axles are trailer tow ready. Limited
slip rear axles on 1500 models require the use of a
limited slip additive (refer to the “Recommended
Fluids, Lubricants, and Genuine Parts” section.)
•The limited slip additive is included with the factory
fill.
•If the axle fluid is changed, 4 oz. (118 ml) of limited slip
additive must be added.
2500/3500 Models
•
The Axles on 2500/3500 Modelsare trailer tow ready
andDO NOT REQUIREany special axle lubes or
additives.
Trailer Towing Recommendations
•
All trailer hitches should be professionally installed on
your vehicle.
•Safety chains must always be used between your
vehicle and trailer.
•Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury. An electrically–actuated electric trailer
brake controller is recommended.
•Trailer brakes are recommended for trailers over 1000
lbs (454 kg) and are required for trailers in excess of
2,000 lbs (907 kg)
•Use an approved wiring harness connector on the
trailer. Standard equipment on all RAM pickup mod-
els provides a 4-way trailer tow connector located
298 STARTING AND OPERATING

under the bumper. This connector contains the follow-
ing 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 provided with the following additional circuits:
backup lamp, trailer battery and electric brake.
NOTE:Connect trailer lighting and brakes using factory
harnesses only. Do not cut or splice wiring to the brake
circuits.
•Be sure the trailer is loaded heavier in front, with 60%
to 65% of the weight in front of the axle(s). Loads
balanced over the wheels or heavier in the rear can
cause the trailer to sway severely side to side which
will cause loss of control of vehicle and trailer. Failure
to load trailers heavier in front is the cause of many
trailer accidents. (For a5th Wheelstyle trailer, this
range of loading on theKing Pinshould be between
15% and 25%.)
•Make certain that the load is secured in the trailer and
will not shift during travel. When towing cargo such
as livestock, dynamic load shifts can occur that require
the driver to maintain attention.
