The negative cable here is the GM part, numbered 86801288.
Build notes: CT4 and Labeled 86801288.
Torque figures belong to the fastener and the joint rather than to the part, so the factory procedure is the reference rather than a general rule.
Confirm the number before you order, because a near match will bolt on and still be wrong. Send the VIN if the old marking has gone.
