Simplest is what Megasquirt call basic trigger using the tacho feed
if the MSD tach output is 12v to 0v with a spike or dip per ignition event there are two options

OptoIn + to the tach feed between the MSD and tacho
OptoIn - to ground
(pins 30 and 31)

the same can be done with VRIn+ and VRIn- (plus to tach feed and minus to ground)
(pins 32 and 33)

later on with a locked distributor, the MicroSquirt VRIn pair can be used with the green wire directly and the microsquirt ignition output then connects to the MSD points input
