Riverrat, good luck with your MH! Wish you many happy miles!
As to your problem, it might be easier if you could post a picture of your water bay panel, so we could look to see what's familiar about the layout. Also, you might have quicker response posting in the owner specific area, where you may find others with your coach. I believe you're made by Coachmen, and they're owned by Forest River, so that might help.
