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.
