They will be in a couple of locations, though I'm not sure of the specifics on your Pace. The chassis electrical system fuses are probably in a box (or two) under the dash somewhere. Will be different on Ford vs Workhorse chassis too.

A phone call to Fleetwood Customer Service would likely get you specific answers for your coach. Have your FIN handy when you call. You can also request wiring diagrams for your coach.
