Video Installation

 

 

BEFORE INSTALLING:

 

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.

STEP 1


Locate fuel pressure and MAP sensor connections above.

 

STEP 2

Pull back gray locking tab on the MAP sensor, depress the black clip and disconnect the factory plug. Referenced above.

STEP 3


Plug the module's MAP connection into the MAP sensor and factory harness. Tug the connector to ensure it's properly connected.


STEP 4

Disconnect the fuel pressure connection located on the driver side valve cover all the way in the back.

STEP 5

Plug the module’s longer clip (male connector) into 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 6


Tug on all connectors to ensure they are properly secured.
