Sorry your first post is about a problem.
I have this picture ; from another member with Fleetwood ,on freightliner chassis . Unfortunately I didn't keep track of the year of his coach, and the actual location. .
The two fuse boxes on the right are Freightliner , the push to reset 12 volt circuit breakers on the left are for Fleetwood installed items.
Note , that starting in 2007 Freightliner went to a gauge and message center , referred to as LBCU ( Light Bar Control Unit ) and there is a change up dash wiring harness to deal with gauge issues.
