Chris - mine is circa 2003 or so, but looks similar to yours. Pretty sure the inputs/outputs/grounds are in slightly different locations. I have the manual -- anything in particular you're trying to sort out? If you like - we can take it to a PM, with your cell or email address I can shoot some pics of the manual and forward to you. As I recall Brian had 2 or 3 different models back then --- the biggest difference being the amperage/current that they would handle, and whether they could also manage an electric water pump.
