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.

Step 1:

Locate fuel rail and fuel pressure sensor.

Step 2:

Unclip the fuel pressure sensor.

Step 3:

Plug the module's longer clip (male connector) into the truck’s fuel sensor that you just unclipped (female connector). Next, plug the module's shorter clip (female connector) into the truck’s fuel rail (male connector).

Step 4:

Mount module away from hot and/or moving parts. Zip ties provided.

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.
