GETTING STARTED
Thank you and congratulations on your purchase of a Pacbrake Direct Mount exhaust retarder.
NOTE: Some early 2003 Dodge trucks were built with 47RE transmissions. These vehicles require the program
within the Pacbrake controller be changed. Follow the instructions in Step 30 to change the program.
See Pacbrake bulletin #L5807 for transmission identification
Please check the exhaust brake kit paret number and application information listed below against the vehicle’s model
and transmission model to ensure compatibility before starting the installation.
This manual covers the installation of the following Pacbrake kits. Should your vehicle differ from the description below,
contact Pacbrake Company at 800.663.0096
C14030AT – contains a fixed orifice exhaust brake kit for 2003 to 2004 Dodge trucks, vehicles built up to January 4,
2004 with 48RE automatic transmissions. See note on top of Page 4.
C14046AT – contains a fixed orifice exhaust brake kit for 2005 Dodge trucks with a 48RE automoatic transmissions,
vehicles built between January 5, 2004 and June 27, 2005 (prior to engines rated @ 610 ft-lbs of torque)
C44049 – contains a PRXB (high performance) exhaust brake kit for 2003 to 2004 Dodge trucks, vehicles built up to
January 4, 2004 with 48RE automatic transmissions. See note #1 below

LOCATING AN IGNITION POWER SOURCE
Remove the lower dash panel below the steering
column. Under the lower dash panel, along the left
side of the steering column, runs a bundle of wires that
include three PINK wires with GREY tracers of different
wire gages. These wires should be 12 Volt positive
ignition power sources. Locate the thinnest (16 Gage)
of the three, connect the “T” tap provided, then connect
the “T” tap to the 3 Amp inline fuse of the Pacbrake
harness.
NOTE: Check the circuit with a volt meter for
ignition power and 12 Volts prior to attaching the
“T” tap. Using the BLUE “T” tap supplied, attach it
to and ignition power source and then connect it to
the supplied fuse harness.
2
Locate the plastic plate in the driver side of the firewall.
Drill a hole large enough to feed the Pacbrake harness
(C20205 or C20219) through, then feed the harness
into the engine compartment from the cab side.
NOTE: Some installers remove the plastic plug to
drill the hole and feed the harness through, then
reinstall the plate.
3
Mount the Pacbrake control unit to the aluminum
bracket on the inside of the firewall as shown. Connect
the two connectors of the Pacbrake harness into the
Pacbrake control unit. Once the harness is positioned
and secured, with the straps provided, apply silicone
around the loom to provide a seal.

Dash Switch Installation
Consult with the owner or operator for their preference
of the location for the Pacbrake ON/OFF switch.
The dash switch location shown in Photo 1 is a
suggestion. Pacbrake offers an optional transmission
gear selector lever switch bracket shown in Photo 2.
Contact Pacbrake customer service to purchase. If
installing the switch into the dash panel, drill a ¼” hole
to accommodate the switch. Install the dash switch and
identification plate, then route the wires towards the
driver side of the firewall to be connected later in the
installation (STEP 17).
5
Connect the GREEN, WHITE, BLACK and RED wires
of the dash switch harness (installed in STEP 2) to the
corresponding coloured wires at the GREY connector
for the controller, (as shown in the schematic on
PAGE 3). Once crimped, heat the connector to provide
a water tight seal. Secure the Pacbrake wires using the
tie-straps provided reinstall the lower dash panel.
6
Disconnect both negative battery terminals.

Photo 2
In the engine compartment, Route the leg of the
Pacbrake harness with the BROWN, ORANGE and
BLUE wires down the driver’s side frame rail to the
transmission connector (shown in the photo). At the
connector, locate the ORANGE with BLACK tracer wire
in Pin #7. Cut this wire in a convenient location to install
the butt connectors provided. Connect the ORANGE
wire of the Pacbrake harness to the transmission side
of the ORANGE with BLACK tracer and connect the
BROWN wire of the Pacbrake harness to the harness
side of the ORANGE with BLACK tracer.

Locate Pin #6 at the transmission connector. It should
be DARK GREEN with a TAN tracer. Cut this wire in
a convenient location to splice the BLUE wire of the
Pacbrake harness into the DARK GREEN factory wire.
The butt connectors provided are heat shrinkable – they
need to be heated after crimping the wires to provided a
water tight seal.
NOTE: If the wire color in the transmission
connector don’t appear to be correct, ensure the
pin location is correct. It is not uncommon for the
VOEM to change wire colors in mid-production.

NOTE: Early 2003 vehicles will have 3 connectors
at the PCM. The PCM is located on the passenger
side of the firewall. For all vehicles with the PCM is
located on the passenger side of the firewall. For all
vehicles with the PCM ion the firewall follow
STEP 8, all others proceed to STEP 9.

EARLY PRODUCTION 2003 VEHICLES ONLY:
Locate the PCM connector C3, remove the protective
cover. Locate the ORANGE with WHITE tracer wire
found in Pin 13. Cut this wire in a convenient location
to splice in the YELLOW wire of the Pacbrake harness,
using the heat shrinkable butt connector provided.
Crimp two wires in one end of the connector and one
wire in the other end, heat the connector to provide a
water tight seal.
9
LATE PRODUCTION 2003 – 2005 VEHICLES:
Vehicles without the PCM on the firewall, connect to
the engine ECM on the driver’s side of the engine
below the intake manifold. The engine ECM has two
connectors: the front connector is 60 Pin and the rear
is 50 Pin. In the 50 Pin connector, locate the DARK
GREEN wire in Pin 13. Cut this wire in a conveinient
location to splice in the YELLOW wire of the Pacbrake
harness, using the heat shrinkable butt connector
provided, crimp two wires in one end of the connector
and one wire in the other end. Heat the connector to
provide a water tight seal.

Locate the factory 3 Pin Weather-Pac connector
on the driver’s side of the engine (shown by the
arrow). Remove the protective cap and install the
mating connector in the Pacbrake harness. Install the
protective cap removed on the unused connector on the
Pacbrake harness – unless you have a performance
module connected to it. If so, connect the performance
module to the mating connector of the Pacbrake
harness.

EXHAUST BRAKE INSTALLATION
Installer Option (not mandatory)
Some installers remove the front wheels and 8 screws
which secure the wheelhouse splash shields. Doing
this allows for easier access to the exhaust elbow. To
remove the wheelhouse splash shield completely, the
ABS cable will need to be disconnected from the splash
shield.
CAUTION:
If removing the front wheels for easier access,
make sure the vehicle is supported properly.
12
Remove Factory Elbow
At the turbocharger locate the 2 “V” clamps fastening
the exhaust elbow to the turbo and header pipe. To
prevent damage to the threads when removing, apply a
drop of oil as close to the nut as possible, then remove
both. Save both “V” clamps for re-use. The factory
elbow is indexed with two roll pins. These pins should
remain in the elbow, if not, they MUST be removed from
the turbo outlet flange. These are for alignment of the
elbow at the truck assembly plant and are not required.
Inspect the sealing face of the turbo for carbon or other
imperfections. If necessary, clean or repair to assure a
good seal will be made as no gaskets are used.

Pg. 7
Dodge 2003-2005
CAUTION: When installing the PRXB Exhaust Brake, use care when handling the brake assembly to
not damage the regulator spring and lever arm.
13
With the original turbocharger to elbow “V” clamp
placed loosely over the turbocharger outlet, insert the
Pacbrake housing into the exhaust system and rotate
the housing until the turbo flange and the exhaust
brake’s pressure flange are parallel. Install the turbo
clamp loosely first, and then rotate the Pacbrake until
the outlet flange aligns with the header pipe. Once
proper alignment is achieved torque the turbo side
clamp to 75 in-lbs (or 8.5 N•m). Now install the outlet
side clamp and torque to 100 in-lbs (or 11.3 N•m).
14
AIR COMPRESSOR SUB-ASSEMBLY:
Locate the poly bag containing the air compressor
mounting bracket, fasteners and mounting hardware.
Place one M10 flat washer on each of the two M10
capscrews. Insert one capscrew into the ring terminal
(air compressor/solenoid ground) of the air compressor
electrical harness.
15
Install the two capscrews into the bracket assembly as
shown. Make note of the mounting bracket cut out, as it
MUST be to the right side.

Using the four 10/32 x1” machine screws, eight #10
flat washers and four Nyloc nuts LOOSLEY attach the
compressor to the bracket as shown, Compressor head
must face the opposite side from the cut out on the
bracket, machine screw must be installed as shown in
the photo for STEP 8 (threaded ends pointing upwards).
Ensure the leg of the Pacbrake harness is between the
air compressor and the mounting bracket.
17
Tighten the four mounting screws and nuts until the
washers first contact the isolator and then tighten TWO
additional turns. Do not over tighten.

COMPRESSOR INSTALLATION
Remove the four capscrews indicated in the photo with
arrows (three with BLACK arrows and the one with
a WHITE arrow). Not all vehicles will have the three
forward capscrews shown in the photo; therefore the
removal will not be necessary. Vehicles without the
forward capscrews require two long spacer tubes and
those with the capscrews will require two short spacers,
both lengths are provided.
Remove the capscrew holding the oil dip stick tube
down (shown with the WHITE arrow), discard this bolt,
a new fastener and spacer will be installed in STEP 20.
I N S TA L L AT I O N M A N U A L - L 5 7 4 3

Position the correct length spacers in the locations
shown in the photo (with arrows). All installations
require the small O.D. spacer on the air intake horn.
NOTE: An engine with the forward capscrews is
shown in the photo
20
Install the compressor assembly over the 3 spacers.
Obtain the best clearance of the compressor to coolant
hose and compressor to intake horn as possible.
Torque the 2 large capscrews (shown with the arrow,
under the compressor) to approximately 32ft-lbs,
(43 N•m). Torque the allen head capscrew to 18 ft-lbs
(24 N•m). Place the spacer provided over top of the
mounting hole for the oil dip stick. Using the longer
M8-1.25x30mm bolt, spacer and flat washer, secure the
dip stick tube to the intake horn, torque to 15ft-lbs,
(20 N•m). Install the pressure switch using thread
sealant, into the open port on the compressor assembly
as show in the photo.
NOTE: The blind threaded port on the compressor
head facing the front of the vehicle remains open.
21
Install the Black nylon airline provided to the solenoid
port marked “CYL”. Route this airline around the front
of the engine to the exhaust brake air cylinder, keeping
it away from heat sources and moving parts. Install the
90˚ fitting supplied into the air cylinder using thread
sealant and connect the airline. Cut the airline to length
with a sharp razor knife. Secure the airline with the tiestraps provided.
CAUTION: This kit includes “push to connect”
airline fittings. They require the end of the airline
to be round, square and cleanly cut to ensure the
internal seal will not leak. The airline must only be
cut with a sharp razor knife or hose cutter

Under the hood, route the leg of the Pacbrake wiring
harness with the two Weather-Pac connectors to the
air compressor. Connect the female connector to the
male connector at the compressor and connect the
male connector to the female connector at the pressure
switch. Secure the harness with the tie-straps provided.
23
Install the ¼” NPT-¼” push on barbed hose fitting on to
the plastic filter housing. Locate the 6ft. blue nylon hose
marked “air intake” and connect one end to the barbed
fitting on the intake filter. Install the compressor air
intake filter into the hole located in the radiator support
bracket behind the driver side headlight (as shown in
the photo). Route this line up to the compressor, and
connect the other end to the push to connect fitting on
the bottom side of the compressor.
24
Install the ¼” NPT to ⅛” NPT nipple into the air tank.
Install the two push to connect airline fittings into the
ends of the tee fitting. Install the tee fitting on to the top
of the nipple, as shown in the photo. Install the ¼” NPT
plug fitting or drain valve (optional) into the bottom of
the tank. Apply thread sealant to all fittings installed.
Air leaks will cause the compressor to cycle more often
reducing its life expectancy.
25
Choose a location to mount the air tank such as
on the driver’s side bumper support brace (shown
in the photo). Drill two ⅜” holes on 3¼” center to
accommodate the tank mounting holes. Provided are
two spacers and fasteners for mounting. If you prefer
another location to mount the air tank, the airline
provided may need to be substituted for a long piece.

Connect the 8ft. airline to the remaining fitting at the
compressor. Route it to the top of the air tank. Cut the
airline to length with a sharp razor knife. Connect the
¼” airline to either fitting in the tank. Secure the airline
away from moving parts and heat sources using the tiestraps provided. Using the remaining length of airline,
connect one end to the remaining fitting in the air tank,
consulate the customer for a preferred location for the
quick connect airline coupler. Route this air line to this
location and connect to the coupler.

CHECK OPERATION AND CONTROLLER PROGRAMMING
Check the Pacbrake system for air leaks. Turn the ignition to ON, the air compressor should pump to fill the
air tank, once the air tank has reached full operating pressure the air compressor must NOT cycle until the
exhaust brake is activated. If the air compressor cycles, check and repair any air leaks.
All controllers come pre programmed for 48RE transmissions (two ORANGE wires approximately 6” from
controller are disconnected).
Early 2003 trucks with 47RE transmissions should connect the two ORANGE wires originating at the GREY
connector. Early 2003 trucks with 47RE transmissions which have been modified with aftermarket valve
bodies and aftermarket lock-up torque converters which are able to hold lock-up during exhaust braking in
1st and 2nd gears can use the later 48RE programming. The difference between the two programs is that
the 48RE transmission program will allow exhaust braking in the 1st and 2nd gears, where the factory 47RE
transmissions will not. Modified 47RE vehicles should test drive the vehicle. If lock-up will not hold during
the exhaust braking in the 1st or 2nd gear, re-connect the two ORANGE wires. To verify program within the
Pacbrake control unit, simply turn the ignition ON, with the exhaust brake switch OFF. If the exhaust brake
cycles 2 times, the 47RE program has been loaded (ORANGE wires connected). If the brake cycles 3 times it
indicates the 48RE program (ORANGE wires’ disconnected).
NOTE: All vehicles with 48RE transmissions should have the ORANGE wires disconnected.
LED SWITCH OPERATION
RED LIGHT – Air system charging/charged, waiting for torque converter lock-up
GREEN LIGHT – Torque converter locked up, exhaust brake will apply then throttle is released
ORANGE LIGHT – Exhaust brake is activated
No Illumination – Brake disabled/OFF
The exhaust brake will not activate unless the LED light is GREEN. This is to protect the transmission. In
certain conditions it will be necessary to apply light pressure to the accelerator to achieve torque converter
lock-up, most commonly after downshifting.
FEATURES
The Pacbrake control unit has a built in warm-up feature. This feature will activate the exhaust brake at idle
with the vehicle stationary when the Pacbrake switch is turned ON. When the coolant temperature reaches
170°F or 75°C, the control unit will disable the warm-up feature at idle. When performing a road test, the O.D.
(overdrive) switch must be in the OFF position and the Pacbrake switch in the ON position. Some vehicles
may have TOW/HAUL instead of O/D, if equipped, turn ON the TOW/HAUL feature with the Pacbrake switch
in the ON position. Attain road speed above 40 MPH or 65km/h and release the accelerator pedal. The
exhaust brake should apply, slowing the vehicle. Once the exhaust brake has brought the vehicle’s engine
speed below 900 RPM, the exhaust brake will disengage. When using the auxiliary coil hose for inflation, the
Pacbrake switch must be turned ON with the engine running for compressor activation.
