I tried moving it flat on the floor (in front of the weird hump) with the cylinder all the way back; It is just too far forward and can't connect to the pedal. If I raise the front of the unit with a piece of wood level with the weird hump in the back the cylinder pushes too directly at the pedal, the top of the pedal mount rocks away. It was designed to push up towards the pedal, not directly at it at 90 degrees so that doesn't work either.
I can put something behind the machine to keep the back from sliding upwards and backwards, I just don't know if having it at that angle effects the braking logic. I know my Techonsha brake controller doesn't care what angle it was at and it worked, hopefully this thing is OK in that same manner.
Perhaps I've found the first car that this thing will not work, problem is the place I bought it has a 20% restocking fee, so returning will cost me over $200 for nothing. That's not RVI's fault, but it sure is bad for me.
I'll call them Monday, I tried today, they don't work weekends.
