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.
