This is what I found But I didn't search all that much.
If you what to make sure it is the right one I would check with a Winnebago dealer. Better yet, give Lichtsinn RV in Forest City , IA a call. They are 1 mile from the factory & only deal with Winnebago products. 1-800-343-6255 You can't buy parts from the factory. You have to go through a dealer. I have bought a lot of parts from them.
Also if you go Winnebago's website click on Resources
. There you will find any thing you want to know about wiring , plumbing & etc.
