Update, I have picked up a fan that needs the controller, there were shed loads on ebay at super cheap prices. The older types were there but not many and similar prices for a fan that has done more work, I may still get one to experiment at a later date.
I was thinking about hooziewhatsit's controller and my concern about electronics in off road vehicles, and remembered I carry a spare VC fan any way!
So what the heck, I have contacted hooziewhatsit via his company web page, it seems his controller may work with (or part of it) my present dashboard indicators. I sent an e-mail throwing in one or two questions with regards to one or two adaptations or add ons.
