Check out under that black cover to the right of the BIRD device...........heavy red cables on each end. Looks like one.
Ignore that post..............I thought I was locked on another post I was working on! Sorry!
Your question was right next to one I was working on and clicked on yours by mistake. As far as your question goes, I would get a complete set of wiring diagrams from Fleetwood and see what those show. I am adding a link for that site for you. I will opt out of this question so another tech can offer something. Don't respond or it keeps me locked in. Sorry for the error! http://www.alliedrecreationgroup.com/service/manuals.asp
