I agree with Dave, if it's your first time do whatever you can to remember what you take from where. After you do a few it becomes second nature, but your first can be a scary experience. I used to use masking tape and mark all the wires that I seperated as to where they went, that may be another way to go about it. You should have a Chilton's, Haynes, Climber manual of some kind and if you don't I would go get one. It will come in handy for all kinds of crap, I probably have 30 of them from different cars and truck I have owned over the years and still keep them around.

Either way, try to mark your stuff as you disassemle so you know where to get it back together, other than that, unbolt it and pull it.
