I also have a 2002 Windsor, congratulations on your coach, I'm sure you will enjoy it, I know we enjoy ours.
Here is a schematic of the electrical bay with parts list. Back about 5 years ago Monaco didn't have their dealer website secure and there was a link posted where you could get information on your specific coach. I was able to download ~100 pages of parts specific to my coach. The parts page in most cases has the vender part numbers so I am able to search for these parts and normally can find them.
Also, if you don't have it go to the Monacocoach.com website and get an PDF of the manual and brochure
Also, if you have a specific problem with your coach you can go to the contact us site and fill out a form for parts or technical assistance.

I had a problem last month and requested hydraulic schematic for my cooling fan system, they sent it within 2 days and then followed up with a phone call.
Also, if you go to the IRV2 Owners section there is a Monaco forum specific to our coaches. There is also a group on Yahoo >> Monacoers which has a group of very knowledgeable people.
I also requested a PDF copy of all my wiring schematics, since you can zoom in on these and search the labeling it is a lot easier to figure things out.
