I'v deffinetly decided I'm going to go megasquirt II. I want to have the MSII control ignition timing. I just ordered a DSII single vac distributor, cap and rotor. I'v read the directions on how to hook up the signal to the coil from the MSII connection to the - side of the coil, but what do I do with the DSII wiring? do I need a MSD 6A or a DSII ignition modual to feed into the MSII?

well I THINK that you piggy back the DS into the MS box. are you going to lock out the timing?
well if you lock out your dizzy then you can do full timing tables on the MS box. I am not sure if there is a way to go half and half with it (really there is nothing to be gained doing that way either) you would have to check the MS forum for sure but the DS2 dizzy would trigger your EFI and all for the MS bos and the MS box would trigger the DS box to fire the coil. similarly you could have it fire a TFI module or HEI mod to fire the coil.
so are you doing a full efi setup?

I just got thinking. if I run the output of the duraspark box that normally goes to the coil, to the input connection on the MSII and then run the output of that to the - side of the coil, this will work right? also, what ignition coil will I need. would an MSD Blaster 2 be a good choice, 1 for stock ignitions? or the 1 for Duraspark?
On MSII the distributor signal is sent to the VR input on the DB37 connector. You have to lock out the vacuum and mechanical advance on the distributor. Install the high current driver per instructions. Coil is then attached to the IGN output (pin #36) from the connector. No external box is required as the coil is fired from the MSII VB921 driver directly.
You can add an MSD to the MSII if you want, but you can ditch the DII box completely. You fire the MSD using the white wire attached to the DB37, same pin #36.
The MSII we've built is running from a Hall sensor and firing a TFI coil directly with no ballast resistor. The VB921 is capable of handling up to about 8.5 amps, so should be no problem even with the low impedence coil. We've set the dwell to a reasonable level which helps keep the current down.

Read the megamanual thoroughly. It's all in there. The purple and orange wires from the distributor go to the DB37 at pin #7 and #24 as in the diagram below.
to lock the distributor, you'll have to diassemble it to either weld or screw the advance weight into place, remove the vacuum canister, then pin the advance plate so that it can't move. All you advance will be handled by the computer and its important to make sure the distributor is not moving.

you can also run a EDIS setup off a ford v6 pretty easily (and get coil pack ignition)
