Len, Winnebago has full wiring diagrams for all their RVs. Just go to winnebagoind.com and click on Resources. That should get you to the listing for each RV. One note: the diagrams (and parts, etc) are in a handy 3D format but it requires MS Internet Explorer and then you have to download a helper app to the browser. Otherwise, you can't see the diagrams. When you first visit the page with wiring (or parts) you'll see a link to download the browser addon.
