The negative Battery Cable change starts by removing the negative Battery Cable first followed by removal of the left front wheel house panel if required. Vehicles with 4.8l, 5.3l, or 6.0l engines require you to remove the Battery Cable bracket bolt and bracket from the Power Steering Pump and disconnect the accessory power fuse block front wiring harness electrical connector from the negative cable connector. Remove the negative cable clip from the positive cable clip as well as the engine wiring harness ground/negative cable bolt. Lift the vehicle before you find a stable supporting position. Vehicle owners must remove the negative cable clip from the positive cable clip before using a crane to lift and support their vehicle for removal of the engine wiring harness ground/negative cable bolt. Vehicles with an 8.1l engine must follow this procedure and then replace the wiring harness ground/negative cables. First remove the forward lamp wiring harness ground/negative cable bolt by lowering the vehicle before removing the negative Battery Cable. Begin by installing the negative Battery Cable and raising the vehicle while positioning the negative cable and forward lamp wiring harness ring terminals to the frame. Also insert the anti-rotation tab on the forward lamp wiring harness into the frame hole. Secure the forward lamp wiring harness ground/negative cable bolt through a torque of 9 n.m (80 lb in). Install the engine wiring harness ground/negative cable bolt with a torque of 25 n.m (18 lb ft) while making sure the negative cable anti-rotation tab is properly positioned. Lower the vehicle after positioning the negative cable clip against the positive cable clip and position the engine wiring harness ground below the negative cable ground. If your vehicle uses a 4.8l, 5.3l or 6.0l engine you must attach the negative cable and engine wiring harness ring terminals to the engine block while positioning the anti-rotation tab correctly before installing and tightening the engine wiring harness ground/negative cable bolt to 25 n.m (18 lb ft). Finish installation by fitting the negative cable clip to the positive cable clip, attaching the accessory power fuse block front wiring harness electrical connector if present, installing the Battery Cable bracket and bolt to the Power Steering Pump if present, tightening the bolt to 25 n.m (18 lb ft), and before connecting the negative Battery Cable install the left front wheel house panel if needed.
