I can't help ya with Ford stuff, but I for one would appreciate you sharing
what you find.

| I'm trying to determine if the EDIS module for distributorless ignition
| (like the 4.6L V8's use) is adaptable to an aftermarket distributorless
| setup.
| What I need to know, are the input and output signals.
| I've been told that the EDIS spark-sorter "module" accepts two inputs:
| cam position, and the spark signal from the ECU. Outputs are 4 wires
| driving the 4 coils.
| It is my understanding that no timing functions occur in this module, it
| is a straight spark-sorter/coil driver that allows the ECU to handle
| timing via the pulse train on one input, and syncs to the engine via cam
| position sensor on the other input.
| Is this correct? Does anyone know where to find a wiring diagram for
| this ignition?
| I've got the ECU, coils, and coil drivers. I need a "spark sorter" that
| sequences a single-wire timing input to four channels.
| I understand the later (post '96) ECU's actually incorporate these
| electronics internally, and are therefore unsuitable for my application.
| Thanks.
