The only thing the rule book says is "functional neutral safety switch mandatory". Doesn't say park switch. They just want the thing to not take off when you start it. Anyone who says park only is making it up. I seem to recall when I had mine checked, they just wanted to see it not start in any gear position.

As said, if using a stock deal replace or run the wire from the "G" terminal to ground through the neutral switch on the shifter.
