MSnSE Wheel decoder setup...

[JSchlappi82]

Hi! I'm almost ready to build my megasquirt setup, but i stumbled onto a little problem... (again)

I think you guys can help me..

It's going to be a Megasquirt I, v3.0 with the MSnSE code. I want to setup wheel decoder with the 36-1 wheel, and the EDIS coilpack (wasted spark)

On the MSnSE site there is an example of an UNTESTED version of the EDIS4 Replacement. Is there anyone who has this working already?

I have to hook up my VR-sensor to the megasquirt at the DB37 connector. Then i need to fit an extra connector for the extra inputs/outputs, as shown on the MSnSE site. (the DB25 connector)
There already is a VB921 in the megasquirt for one spark output, but in the picture a little lower is described you need to hoop up extra VB921s for spark a/d. (2 VB921s for A and B in my setup?)
Can i hook them up, like showed in the picture i made? And then set spark outputs to be LED17 and LED19?
And where should i ground these for best results?

Thanks for the assistance, Joris.
