here ya go guys.
i doubt this is specifically our engines, but should give valuable information to those looking to wire up spark-control on their stand alones (like myself)
Also keep in mind, that diagram is for Megasquirt. I believe you said you were going with MS-II (Spectre, correct?). If so, then the pin assignments to the MS-II should be considerably different (i.e. pins 25 and 27 are for GM IAC control). Also, there is a writeup in the megamanual pages on how to setup the bypass with MS-II and the earlier generation GM DIS (which is the same ICM as you posted).
