Thanks for the suggestion about rope lights and other accessory lights, shastagary. I found that two of the switches control rope lights along the floor and above the bed. I had not noticed them when I tried it out before. This time I looked more closely. Still trying to figure out the other two switches. I looked over the wiring diagrams and didn't see anything that looked like it was for an American Cruiser. I have the wiring diagram or the Dodge van (Haynes) but not for the conversion. But thanks for the suggestion and effort, 1995brave.
