2020-2022 6.7L Powerstroke Installation
Step by Step Instructions
Be sure your truck has been off, with the hood unlatched and key fob located away from the vehicle for at least 15 minutes before installing the module. Key fob needs to continue to stay away from the vehicle for the entire installation process. This allows the computer to 'sleep' and for your engine compartment to cool down. It also helps mitigate your ECM from detecting an interruption in a sensors electrical circuit.
Locate the fuel pressure on the driver's side of the engine behind the alternator.
Disconnect plug from the fuel sensor. The fuel sensor has a locking tab. We recommend using a hook style dental pick as pictured in order to disconnect the plug. The locking tab will slide towards the front of the vehicle to release. Then squeeze connector and gently pull on the plug to remove it from the sensor. Plug the module's male connector into the truck's female connector.
Plug the module's female connector into the fuel sensor. Tug on each connector and make sure they are snapped over the sloped tab.
Ensure connectors fit snugly and loose wires are tucked away. Gently tug on all connections to make sure they are secure especially the fuel pressure plug.
The module and switch must be installed away from heat and moving parts.
How The Selector Switch Works
The dial going clockwise:
Stock - Low - Medium - High
Low: Towing heavy and low traction situations.
Medium: Moderate towing and ideal for everyday driving situations.
High: Maximum performance - ideal for empty highway cruising.
The switch must remain plugged in to stay in the desired setting. You can run the switch into the cab or leave it tied up under the hood. Leave in one setting as much as possible.
Everyone has different driving preferences, it’s suggested that you try each setting for at least a week to see what you prefer.
If You Get a Check Engine Light or Hard Start Upon Installation
Please check the connection between the truck’s wire harness and the module’s female plug and ensure it was connected properly. Improper installation will cause a CEL/hard starting.
Remove The Module Before Service Work
If you need to take your vehicle in for service work, REMOVE the module before work is performed.
