Ok, I think I have it down to one question after the m6 to a4 swap. I wired up the TCC brake switch and that seems to be working, but the converter still isnt locking up.

I figure maybe the Neutral park switch may have something to do with it. I have an aftermarket shifter so I have to figure out that switch. I know i need to use 230 "J" going to C15. Does this take 12v power or just need to be grounded?

Thanks
