NXT (550) & MC-40 Harness?

[Worldwide Gaming]

Does anyone have any information on how to correctly connect an MC-40 (Personality 14) in place of an old CC-16D on an upgraded 550 to NXT machine?

It got the standard 550 Optics (3 pairs of xmit/rcv & a 4-pin connector).  The CC-16D worked fine reading just the Sense info but the MC-40 outputs Sense, Tilt, and Credit.  I've tried each of those outputs into Pin 1 on the WMS, but all cause an error.  Also spoke with Coin Mechanisms regarding timing of pulses - but unfortunately, they did not have the info for the NXT available - just their own MC-40...

On the WMS side:
1 - Input/Sense
2 - Output/INH
3 - Output/12VDC
4 - GND

On the MC-40 PR14 INHHI:
1 - GND
2 - Output/Sense
3 - Output/Tilt
4 - Output/Credit
5 - n/a
6 - Input/12VDC
7 - Ctrl-In/INH

The old CC-16D was wired as follows:
1 - INH
2 - SENSE
3 - n/a
4 - n/a
5 - 12VDC
6 - GND
