Removal Procedure

    • Always use replacement cables that are of the same type, diameter and length of the cables that you are replacing.
    • Always route the replacement cable the same way as the original cable.

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.

    • Disconnect the negative battery cable from the battery before proceeding with any replacement or repair.
