Step by Step Instructions
Be sure your truck has been off for at least 10 minutes before installing the module to allow computer to "sleep" and for your engine compartment to cool down. This way it will not detect an interruption when you unplug your sensor.
Locate the (2) injectors harness plugs on the driver's side of the valve cover on the top of the engine. The connections are labeled: "Flywheel harness" for the rear and "Engine harness" for the front connections.
You may require a small screwdriver to release the connector retaining tab. If using a screwdriver to release the locking tab, GENTLY slide into lock and push it towards the valve cover to disengage.
Note: It may be beneficial to remove the foam around your fuel rail to help with access to the rear injection harness plug.
Once the harness plugs are all connected you can connect the red wire to the positive terminal and black wire to the negative terminal of the driver's side battery.
Now that the entire harness is installed in the truck, double check that all connections are secure and flush. Then plug the harness into the module.
Mount module away from hot and/or moving parts. Zip ties provided.
We recommend storing the module in the pocket behind the battery.
Medium is the best all-around setting to leave it in. Please allow up to 100 miles for the program to engage.
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.
