EDIS to coil confusion
contaminated - 11/6/09 at 02:39 PM

I've seen a post on here about this subject and specifically relating to a right way and a wrong way of wiring up the EDIS 4, but I can't find a definitive answer. Which pins on the EDIS go to which pins on the coil plug. Some diagrams have EDIS pin 10 to Coil 1 and EDIS pin 12 to coil 3 and some have it the other way around. Anyone know which is right?

This one? Rescued attachment EDIS_Module_harness.png

top one is correct, I believe.

That's interesting becasuse it came from the autosports website, yet differs to the one I was actually sent with the MJ.

I'll have a look at the wires later (as done by Mr Ford in 1992 )

I took the whole tree from a fiesta, so didn't have to worry about this, but it doesn't matter much. If it's not right, then just swap the ignition leads (1 on 2 and 3 on 4 and vice versa)

Well I think 12 joins to 3 and 10 to 1 (going by the numbers writen on the plugs themself)

but I'm red/green colour blind so what do I know

here's the pics linky 1

As I understand it , it dosnt matter which way round they are - all thats happening is two coils are being fired alternately .
Neither the coil , the edis or the megasquirt care weather they firing 1+4 or 2+3 - it wont make the slightest bit of difference to how it runs .
Unless you already have the plug leads and they will only fit one way around........
It apparently matters on a 6 cylinder coil due to heat build-up , but mine is wrong (found out after I had spent £125 on plug leads ) , I didnt change it and 18 months later still no problems

Thanks all - appreciated. I agree that in the scheme of things it doesn't matter really, but I have fitted plug leads that need to be in a certain order.
