Notice: The BCM electrical connectors are designed with tabs and slots that allow the connectors to only fit one way. The connectors do not require excessive force if being installed correctly. Installing the connectors with the wrong mating half or upside down can cause damage to the connector, the BCM, or other vehicle components or systems.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
