2003 Z4 remote top project

There was a recent thread over on E46fanatics about getting the older E46 3-series cabs to raise and lower their tops using the key fob, a feature the 2003 Z4s are also missing. Piggybacking on that information, I plan to try the same modification to my Z4 tomorrow. What I'm hoping is that someone here (okay, Ron) can confirm I've got the pin-outs right. The plan is to use the following:

Down Module
White - pin 20 (unlock signal detect)
Green - pin 51 (signals top motor to lower)
Red - pin 47 (power)
Black - runs to Up module, sharing Ground connection on pin 10

Up Module
White - pin 22 (lock signal detect)
Green - pin 13 (signals top motor to raise)
Red - runs to Down module, shares Power connection on pin 47
Black - pin 10 (ground)

I'm going ahead tomorrow morning, just looking for a bit of confirmation/reassurance before I begin.
