EDIS WIRING!!!
Me and scott C started wiring up the zetec last night and a few wires came a bit confusing
1st we cant understand how the edis is wired or is required to be wired to the mega squirt- can anybody tell me why in the diagram it is shown to be a
switched live connected directly to earth???

Found this
PIP (EDIS output signal) Pin 1
IDM (diagnostic signal to ECU) Pin 2
SAW (ECU spark control signal) Pin 3
IGN GND (signal return) Pin 4
VRS - (crank sensor negative) Pin 5
VRS +(crank sensor positive) Pin 6
VRS shield (crank sensor shield) Pin 7
VPWR (ignition switched 12 volts) Pin 8
PWR GND Pin 9
COIL 1 (coil drive) Pin 10
CTO (clean tach out) Pin 11
COIL 2 (coil drive) Pin 12
From here

NO8 on the edis is connected directly to 2 on the coil!!!
no 2 coil is ground and 8 is 12v

Eureka you solved my problem I wondered why pin 8 is a direct short to earth as well as powering the coil . it's only earthed through a
supressor if fitted .......that has saved a lot of sparks bangs and misery
