NOTE: The following instructions assume that the
vehicle already has a Fleece Performance Engineering
2nd gen kit installed on the vehicle along with an S400
turbo with appropriate 4 5/8” OD flat V turbo outlet
flange. The exhaust manifold must be the downward
direction.
NOTE: If your 2nd gen kit is of an older vintage, you
may NOT have installed a coolant riser delete
originally with your kit. A coolant riser delete is
required for use with this kit. NEW 2nd gen hardware
kits available from Fleece Performance include the
coolant riser delete kit.
STEP 1: Drain engine coolant and remove the
passenger side front inner fender well.
STEP 2: Remove the originally installed FPE exhaust
downpipe from the turbo housing and exhaust
system.
STEP 3: Assemble the exhaust brake valve to the cast
elbow using a V-band (item 4). Based on your turbo,
alignment pins on the cast elbow may be used or
removed by using a pair of pliers to pull the pin
outward. Not all turbos are configured to allow for
use of the dowel pin.
Install the two M12 x 1.0 inverted flare plugs onto
either side of the exhaust brake housing. These two
ports are unused BUT CAN be used for a back-
pressure sensor if desired for monitoring back-
pressure. Remove the two red plug caps for the
cooling ports and install the two -6 to 9/16”-18
straight male w/ O-ring fittings onto the exhaust
brake cooling ports.
STEP 4: Install the exhaust brake valve and cast elbow
to the discharge of your turbocharger using a V-band
clamp (item 4).
PROCEDURE:
STEP 5: Locate the coolant port on the engine block
located to the front of the oil filter housing that
supplied the factory VGT turbo with coolant. Remove
the installed block off plug (typically a socket allen
head) and install the appropriate -6AN fitting and
sealing washer for your engine. Two sizes are provided
in the kit, a 18mm and a 16mm - you will only use one.

STEP 6: Install the coolant riser delete hoses IF
REQUIRED. Reference our installation instructions for
the coolant riser delete kits on our website or by
clicking here. Select a location just to the rear of your
battery box to cut-in the ⅝ to ⅜ adapter tee and hose
based upon your routing. The location will depend
upon how you have routed your coolant line from
the riser to the firewall.
If the truck already has a Fleece coolant riser delete
installed or an after-market coolant tank, install the
⅝” to ⅜” adapter tee and hose at any point in the
hose that works best for your routing. The image to
the right shows the new adapter tee for the exhaust
brake installed between the coolant tank and coolant
riser delete adapter tee.

STEP 7: Install the -6 AN hose (item 13) provided with
the 45 deg fitting to the engine block and the 120 deg
fitting to the front port on the exhaust brake.
Next, install the hose from the adapter tee to the
rear port of the exhaust brake using the 90 deg
fitting.
STEP 8: Install the lower portion of the downpipe
back into your existing exhaust, attach the downpipe
to the cast elbow with a V-band clamp (item 4).

STEP 9: Plug the exhaust brake’s electrical connector
into the OEM’s original VGT connector. Plug the
other end into the pigtail on the exhaust brake. This
connection provides 12v power to the actuator.
Reference page 10 for an electrical harness diagram. STEP 10: Route the two wire CAN signal along the top of the engine bay, securing it to the firewall or existing OEM cable looms. Cut a slit in the firewall cable pass-through located to the right of the steering column (as viewed from the engine bay). Route the two-wire CAN signal line through the firewall pass-though and plug the CAN signal connector into the OEM communication junction block. It will contain green two-pin receptacles. You can use any open port on the junction block that contains yellow wires. You must use the CAN block that contains the yellow wires – the other CAN block with white wiring will not work. If you choose the incorrect CAN block, the engine will not start and DTC’s will be present.
The CAN communication junction block is located
directly under the dash on the driver’s side,
immediately to the left of the steering column and
above the clutch pedal vicinity.
STEP 11: Refill coolant and check for leaks. Re-install
the inner fender well. If removed, re-install any intake
components and connect all sensors.
STEP 12: Operate the vehicle and activate the exhaust
brake switch on your dash.
*Test for proper operation of the exhaust brake as
outlined in “OPERATING MODES AND CONDITIONS”
below.
*Verify coolant flow through the brake assembly by
loosening a fitting at the brake and allowing coolant to
seep. If coolant flow is not present, check coolant level
and line routings.

EXHAUST BRAKE OPERATING MODES AND CONDITIONS
COLD START WARMUP MODE: The exhaust brake will partially close when the following conditions are present to assist
in faster engine warmup.
• Engine coolant temperature less than 150F
• Engine RPM greater than 550 RPM
• Vehicle speed less than 2 mph
• Throttle position equal to 0%
Cold start warmup mode will be disabled if any of the above conditions are not met and will resume if all conditions are
re-met. i.e. – pressing on the throttle will disable cold start warmup mode, releasing the throttle with all conditions
present will allow the brake to return to cold start warmup mode. Cold start warmup mode is always active regardless of
exhaust brake switch position.
FULL-ON MODE: This mode provides for the fastest response time from the brake. “Full Exhaust Brake On” will be
displayed on the dash when selected with the OEM dash switch. The exhaust brake will close when the following
conditions are present for ½ second:
• Throttle = 0%
• ABS is inactive (exhaust brake will not function if any ABS fault or
condition is present)
• Engine RPM greater than 800
• Vehicle speed greater than 10 mph
• Cruise control is not set
• Clutch is not depressed (manual transmission only)
AUTO MODE: This mode will not activate the exhaust brake until the service brake is depressed. “Automatic Exhaust
Brake On” will be displayed on the dash when selected with the OEM dash switch. The exhaust brake will close when the
following conditions are present for ½ second:
• Throttle = 0%
• Service brake is applied
• ABS is inactive (exhaust brake will not function if any ABS fault or
condition is present)
• Engine RPM greater than 800
• Vehicle speed greater than 10 mph
• Cruise control is not set
• Clutch is not depressed (manual transmission only)

TROUBLESHOOTING
SYMPTOM POSSIBLE CAUSES Exhaust brake operates in cold start warmup mode but not during driving or when warmed up.
Manual transmission equipped trucks: The clutch switch has failed or has an intermittent connection and is not toggling between active/inactive states. The truck will start and no DTC’s will be logged when a failed clutch switch occurs. You can view the “Clutch Status” with a scan tool to confirm proper operation, it should toggle between “engaged” and “disengaged”. ABS status: Ensure that ABS is “Inactive”. Ensure coolant lines are properly routed and coolant flow is present by loosening a coolant port connection at the brake. Insufficient or no coolant flow will result in a brake that will not operate at high temperature due to lack of cooling.
Exhaust does not operate in any mode (cold start warmup or during driving).
Check all electrical connections and perform a tug test on the wiring. Ensure all pins are properly seated. Make sure all connections are tight. Confirm you have 12v power at the exhaust brake connection from the chassis/vehicle side. If you do not have 12v power, check your fuse panel. For MY13-18 trucks, 12v power is provided on the red wire (pin 4) and ground is supplied on the black wire (pin 1). High speed communication is on pins 2 & 3.
Intermittent exhaust brake operation during cold start warmup or during driving operation.
Check all electrical connections and perform a tug test on the wiring. Ensure all pins are properly seated. Make sure all connections are tight. Visually inspect all connectors for damaged or pushed pins or terminals.
Dash experiences erratic behavior, numerous DTC’s are present, or the truck will not start after installation of exhaust brake.
Incorrect high speed CAN port utilized. Remove CAN port connection and select the proper high speed CAN port on the truck. See step 10.
