Installation Instructions for Ford Powerstroke 3.0L V6 Stealth Module (2018-2022)

Included With Purchase

(1x) Stealth Module
(1x) Wire Harness with Fuel Rail Sensor Connections
(1x) Selector Switch





Step by Step Instructions

Let your truck sit with the hood popped, doors shut and the key fob away from the vehicle for at least 20 minutes. It is important to keep the key fob away and the doors shut during the entire installation process. DO NOT bring the key fob near the vehicle or open any doors until AFTER the module is fully installed and connections are verified. This allows the computer to 'sleep' and for your engine compartment to cool down. Failure to do so will result in a check engine light on startup.

 Step 1:

Remove plastic engine cover.

 Step 2:

Move rubber insulation aside on the front passenger side of the engine to expose the front of the fuel rail.

 Step 3:

Unplug fuel pressure sensor on the end of the fuel rail. Plug our connectors inline. Pay close attention to the orientation of where our harness plugs into your factory harness. If it is plugged in upside down, it will not clip.

 Step 4:


Zip tie or velcro your Stealth Module in a safe location away from direct heat.
