I got a used VA TF surefit unit (just the under dash part and some hoses) and was able to figure out from the online manual download how it mounts and works. I was missing the cables and replacement fan switch which I ordered from VA. When I got them I found I had an earlier unit and had to modify two of the cable brackets on the unit. Using the instructions and wiring diagram bench tested all the power circuits, micro switches and fan switch. I have found their phone techs friendly and knowledgeable about the product. It would be nice if they had someone available during the weekend when a lot of hobbists are working, but I assume they did a cost benefit and found that the number of calls did not add up to paying someone two days salary. You could probably get you questioned answered here anyway. As for the missing parts a call would probably solve that.
