Video Installation


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:

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.

Sensor Connections

Step 2:

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.

Sensor Connections

Step 3:

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.

*Do not apply backward - it will damage the module.

Sensor Connections

 Step 4:

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.

 Step 5:

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.

Turn Dial Clockwise

Stock - Low - Medium - High

Low - Towing at or near the vehicles maximum legal tow rating and low traction situations.
*consult your owners manual for vehicle tow rates

Medium - Moderate towing, around the middle of your vehicles tow rating, and ideal for everyday driving situations.

High - Maximum performance. Ideal for empty highway cruising.

The switch must remain plugged into the Stealth Module to remain in the desired setting. Do not switch power levels with the engine running.

You will see the best results when the selector switch is left in one setting for as long as possible.

Check Engine Light or Hard start on Install?

The most common reason for a check engine light on install is due to the truck not being asleep. If the Stealth Module has already been removed, please start the installation process over while giving special attention to the instructions above step 1. If the Stealth Module is still installed, verify connections and disconnect the negative terminals on your battery for a hard reset. Events that will wake the truck up: Not letting it sit for 15 minutes, opening/closing the vehicle door, having the key near the truck during install.

The most common reason for a hard start on install is due to improver connection. Please verify that all connections are straight and pushed in all the way. Be sure the harness is pushed in tight to the Stealth Module as well.

Remove the Stealth Module Before Service

Before going in for service, please remove the Stealth Module so that the truck is back to stock. This allows the technician to have a fresh base line when performing any work.
