A Straightforward Guide to Installation

Installing your new ECM is a manageable task for a confident DIYer. Our pre-programming service saves you the most difficult step. Follow this general guide for a successful installation.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
2. Locate the ECM: On the 2008 Buick Enclave, the Engine Control Module is typically located behind the radiator fan shroud. You may need to remove the shroud for access.
3. Disconnect Connectors: Carefully unclip the wiring harness connectors from the old module. Inspect the connectors for any signs of corrosion or damage and clean them if necessary.
4. Remove the Old Module: Unbolt the old ECM from its mounting bracket and remove it from the vehicle.
5. Install the New Module: Mount your new, pre-programmed ECM in the same location and secure it with the bolts.
6. Reconnect Everything: Firmly plug the wiring harness connectors into the new ECM until they click into place. Reconnect the negative battery terminal.
7. Perform Security Relearn: Your vehicle may require a security or anti-theft relearn procedure. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times before starting the engine. Consult your owner’s manual for the specific procedure for your vehicle.
