Well, I don't advise messing with the board, especially with it powered up. The two wires I am talking about should originate on the board, and go to a box in the panel, which is the battery. Some installers route the wire behind the board because they are long, and this keeps it neat. They should come back out from behind the board. The battery will have little terminals on it that are color coded, or are identified in some way as being positive and negative. If you don't see a set-up somewhat similar to what I describe, it may be best to call someone. Don't do anything you don't feel comfortable with.
