Most of the time when people say get an FSM they are simply trying to help. You should have one anyway. It will answer a ton of questions. They are great for exploded diagrams and things like that. The FSM should be as important a tool as every tool in your toolbox. Maybe more so. People who are too hare headed to get an FSM......especially those that are FREE FOR DOWNLOAD I usually just quit helping. The FSM can teach you a TON about your own car.
