Starting to wire Megajolt,EDIS4 and VR for a zetec.
I have an EDIS4 unit with only 11 wires.
The part number is 91AB-12K072-AA.
Is this the wrong one? All the megajolt info shows 12 wires. It came out of a 92 escort XR3i.
Looks as if the no.2 pin/wire does not exist.

It will be the one for the rev counter, use the megajolt for the revs.

If it's the one for the rev counter, then I'm looking at it upside down.
Reading the label (EDIS4) the right way up, is the no.1 pin to the left?
Bill.

Yes on mine it was no 11, and i think it is the white one from the megajolt.

I seem to remeber there was some confusion with the wiring diagram shown on the MJ site about the wiring diagram being backwards. This may be the problem.
