We need information on what year/make/model the bus is. Pics of the fuse panel would be helpful as well. I own a Ford Ward body and a Thomas Saf-T-Liner, neither have the same style of fuse panel. When I get my second Saf-T-Liner, it has a different electrical set-up than the '89 I own.
Waiting for more information........
