I too want to congratulate you on your extinguishment skills.
I am not familiar with your coach but I am with Winnebago. A couple of ways to go is to see if the wiring drawing for your coach is still avail. at Winnebago. You can down load it if it is.
You could also call Lichtsinn RV | Winnebago, Itasca, Winnebago Touring Coach
and talk to their parts department and if it is available these guys can get it. Have you V.I.N. ready and explain what happened.
