Not 100% sure if this is the correct place to put this or not,but i do have questions about this ignition set up.In theory it should work as i have pulled up some diagrams and figured out most of the wiring to a point.But i am not 100% if it will work and i figured id ask here if anyone has any insights or ideas on how to make this work.I know it sounds stupid simple but i am all new to this so im learning as i go but here is what i have below.

^ above is the 6 cyl edis coil pack from a ford,using the +12v then using c2,c3,c1 as igniter references or however you want to put it then this will talk to the 203 module.However the 203 module is wired slightly different from what i am doing but this shouldn't matter.As it still has 3 igniters and im just moving the #5 igniter to the #2 cylinder on the coil pack as my coil pack has no reference for #5.

So in theory this means Pin #3 goes to c2 on the coil pack,and Pin #6 goes to c3,then c1 goes to Pin #1.I don't think the order matters as these are just the ignitors,but i am not 100% sure on this.I would also like to add its calling for another igniter to run the #2 coil but if i have 3 igniters already then whats the point in another module?Should it matter?

I also have the 203 module part # 0 277 100 203 pined out as well below from what i got off the diagram.

Pin#1 Coil 1, Pin#2 ECU, Pin#3 Coil 5 (but im going to use this for #2 on the edis coil pack), Pin #4 module ground? Pin #5 ECU, Pin #6 Coil 3, Pin# 7 ECU,

I am also basing the wiring off the diagram for the 211 module as the wire locations for the signal are the same and the colors are the same on the diagram.

pinout of the 203 module is (found this bit of info on the forums,but that's about it)

1 Coil Negative [ Channel Three ]
2 Switching Input [ Channel Three ]
3 Coil Negative [ Channel Two ]
4 Power Transistor Ground
5 Switching Input [ Channel Two ]
6 Coil Negative [ Channel One ]
7 Switching Input [ Channel One ]

(i have no idea with the above as to how the module is tied into the EDIS coil pack,with this not being explained a little bit better)

I just need all this explained to me how i need to wire all this together and to make it work with ms.Sorry for all the confusion,but at least i am finding diagrams and what not.And posting what i find to help aid the cause.

Far as crank sensor goes ill be using the stock VR sensor that came on the car which was a LH2.2 car equipped with a 60-6 on the flexplate and from what i have found out should work with tunerstudio as the settings are adjustable.

Thanks
