Hello Gene,
I was away on a trip so I have not been on the computer much or the RV net board. I don’t know how your Unit ( 211 ) is wired but here is an idea for you , I wired a 12 volt plug outlet for my 12 volt TV up front in the TV area. I wanted a separate fuse (as you should have) so I wired it from the main fuse panel box which on the 225 is in the back of the RV by the bathroom. I wired it from the box by going up thru my closet up to my cabinet, taking down the panels in back of the cabinets on the wall and ran the wires in back and up to the TV area than put the panels back in place. That way you will have a live ( dedicated fused ) wire for your fan in the front of the RV than you can figure out what you need to do to get it the few inched to the fan from there.
Gene I am not sure if I still have your e-mail address or not. Send me an e-mail and I will send you a few photos of how I ran it forward from the panel.
