Installation Instructions

1. Measure the overall length of your Sentinel Exhaust Brake and subtract 4” (2” on each end) to get the measurement you will cut out of your exhaust pipe. (E.g., If the Sentinel Exhaust brake is 11” in length you will cut out 7” out of your exhaust pipe.)

   

   

2. Locate a suitable place on your exhaust pipe to install the Sentinel Exhaust Brake. (The closer to engine the better. The bottom of the down pipe is recommended.) Mark your exhaust pipe and cut out exhaust pipe section. (Grind or file the ends of the cut pipe so the Sentinel Exhaust Brake will slide on easily.)

3. Slide the Sentinel Exhaust Brake into the cut-out section. (Ensure that your exhaust pipe on each end is fully slid into the Sentinel Exhaust Brake.)

4. Clamp or weld both ends of the Sentinel Exhaust Brake to the exhaust pipes. (If clamping, retorque clamps after exhaust system has been hot at least once.) Note: The Sentinel Exhaust Brake will NOT build optimal back pressure if exhaust leaks are present. Make sure clamps are tight and no leaks between the exhaust brake and the engine exist (welding is recommended if capable).

5. Connect jumper harness to brake connector and safely route jumper harness up the frame rail and across the firewall in the engine compartment. (Ensure that jumper harness will not burn or chafe on any components.)

6. Route the remaining jumper harness through the driver side firewall into the cab. (Usually, the jumper harness can be slipped through an existing harness grommet without too much hassle.)

7. Secure jumper harness with zip ties and tape connector with electrical tape to ensure it does not come apart. (Ensure that jumper harness will not burn or chafe on any components.)

8. Connect main harness to jumper harness and tape connectors with electrical tape.

9. Connect the red wire on main harness to 12-volt power. Connect black wire on main harness to a solid ground. WARNING: Do not connect any of the switch wires to 12-volt power, this will damage the switch controller and the exhaust brake motor. (The exhaust brake motor and controller are powered by a 5-volt reference.)

10. Drill a 13/16 or 20mm hole in dash for switch. (Make sure the switch will be located in an accessible location.) Note: Another type of dash switch can be used as long as it is a ON/OFF/ON stationary switch.

11. Feed main harness switch wire through switch hole and connect the switch wires using the diagram below. NOTE: The switch wires can easily be removed from switch by pressing the metal tabs on the connectors. DO NOT tug or forcibly pull the wires off of the switch.

12. Install switch in hole with the (I) line at the top.

13. Secure main harness and control box using zip ties. (Ensure the main harness will not rub or chafe on any other components.)

14. With the key on/vehicle off, toggle the switch to the (I) position and wait 5 seconds, then toggle the switch to the (II) position and wait 5 seconds. Finally, toggle the switch to the (0) position. Shut key off.

15. The GREEN or WHITE wire coming from the main harness is only needed if you are installing a Torque Convertor Lock-up Harness.

Operation Instructions

• When going downhill or coming to a long stop, toggle the Sentinel Exhaust Brake switch to the (I) This will close the valve engaging the exhaust brake. (Note: The controller on the main harness will ensure the exhaust brake fully closes and will only allow you to disengage the brake after 5 seconds.) DO NOT toggle the switch back and forth quickly.

• When exhaust braking is no longer desired, toggle the switch to the (II) This will open the valve and disengage the exhaust brake.

• To shut the exhaust brake and controller off, toggle the switch to the (0) (Note: toggling the switch to the (0) position when the exhaust brake is engaged will not disengage the exhaust brake, you must toggle the switch to the (II) position to disengage the brake.)

• With automatic transmissions the Sentinel Exhaust Brake performs optimally ONLY in Tow/Haul mode. (Tow/Haul mode locks up the torque converter on your automatic transmission so down-shifting is similar to a manual transmission, causing your exhaust brake to slow you down using the powertrain.
