Owners Manual
BKH,
Welcome to the forum. I have an 89 Winn Chieftain. It had the owner's manual, however, I was able to get the wiring and water diagrams from Winnebago. I just sent them an email and they forwarded files for the wiring and water. They have been super each time I have had to send a request or ask a question. I'd check their WEB site, send customer service an email and go from there. Good Luck
