The original idea for the ignition system was to use a Ford coil-pack and EDIS module.
The megasquirt manual has a great write-up on EDIS if you don't know what it is.

The necessary parts were procured on eBay about 3-years ago at the start of the project, and have been collecting dust ever since.
We fabricated an aluminum bracket to hold the VR pickup at 60 degrees before the missing tooth (at top dead center) as required for "limp mode" of the Ford ignition. The VR sensor bracket mounts to the alternator bracket, with a stabilizing arm that connects to one of the timing cover bolts to help keep it rigid.
Ray Livingston also has a very nice looking setup for the megajolt which I was seriously considering, but I had already done most of the fabrication work by the time I came across this http://etypeuk.com/forum/viewtopic.php?t=437
We got the coil pack and EDIS module wired and sparking beautifully in "limp mode" even with the engine cranking over at very low rpm (<100). Unfortunately when we hooked it up to the mega-squirt the spark went away.
A week later Autozone confirmed the EDIS6 module was working when they bench tested it.... At any rate we had already moved on.

| An aluminum spacer provides a convenient location to bolt the trigger wheel onto the existing damper and space it far enough away so that the VR-sensor wont interfere with the alternator belt or pulley. |

| Nothing appeared to be visually damaged inside the EDIS module when we opened it up. Although we did learn that it is potted in an odd jelly like substance. |
