So close to starting...
I'm so close to starting my engine for the first time. Fueling is now sorted and I'm getting strong sparks. I think I have the firing
order wrong though 
I'm running EDIS and I'm a bit confused about it.
^In this pic the numbers are as they are labelled on my EDIS unit
It's the coil stuff that I don't understand.
quote:
6 cylinder (EDIS6):
On a 6 cylinder engine, the coils in a 6 terminal pack fire ACB (with ABC left to right with the connector on the bottom). Coil A fires first and
should be connected to cylinder #1 and its complimentary cylinder. The coil C should be connected to the cylinder that fires after #1, and its
complimentary cylinder. The remaining two cylinders should be connected to coil B.
For example, with a 6 cylinder having a firing order of 123456 (GM 60° V6), you would connect coil A to 1&4, coil C to 2&5, coil B to 3&6.
On EDIS6, coil A is connected to pin 10 of the EDIS module, coil B is connected to pin 11 of the EDIS module, and coil C is connected to pin 12 of the
EDIS module. If these are connected the other way around, the coils will fire in a different order, and the spark plug wires will need to be
rearranged.
There's no haynes manual for the volvo 960 so I'm not sure of the firing order (and I can't remember where I found it last on the
net) I think it's 1-5-3-6-2-4 so my question: which leads from EDIS go to which cylinders?

The EDIS is paired as well I believe so in your picture 1&5, 2&6, 3&4 will fire when the get a signal from a, b or c (in whatever order
you wire it).
You need to work out which are the complementary pairs in your firing order and the use the edis pairs as needed...
Sorry, doing this from memory as don't have the books with me at the moment...

Very little on the web about your engine but this pdf looks like your
info is ok.

Just to add the numbers on the coil pack are off the cyl numbers not the firing order.
My mate made this mistake when we where wiring his vw.
Its just a case of finding the pairs.
I would try A) 1+6 b) 5+2 C) 3+4

Cant help with your problem but good luck with the start 
Are you going to video it?
How long can i resist the temptation to drop a V8 in?

Pairs,
Its a wasted spark set up so will fire two cylinders at once one on the compresion stroke and the other on the exhaust stroke, hence wasted spark.
So there will be two cylinders that will be at tdc at any one time.

There is an 850 in my local scrapie with a B6304, tempting but it looks huge in the volvo so, 
One on ebay for £200 so thats less than £1 per bhp

The "pairs" are as shown on the coil pack, so 4 & 3 will fire together, 6 & 2 likewise, and the same for 5 & 1, hope that
makes sense. Cheers Ray

Assuming you order 1-5-3-6-2-4
is correct the cylinder pairs are:
1,6
5,2
3,4
Edis 6 firing order from memory i THINK is ACB. It was 2 years ago i did this so not sure if that is correct.
A fires when edis sees tdc - (SAW advance) for cylinder1

So is 1&6 coil A, 5&2 coil B, 3&4 coil C? ^__^

Yeah, in my case 1&6, 2&5, 3&4

I can't see anything that indicates the pairing, just numbers 1 to 6 :S

Edis info
I recon the order should be from checking the above url
Coil pair : CYLINDERS : Edis module pin no.
A 1,6 10
B 3,4 11
C 5,2 12

Thanks what i recon. I have edited my post to correct the edis pin numbering/ coil letter
coil A is pin 10, coil B pin 11, coil C is pin 12.
Look at the link to check, near the bottom for edis fitting to confirm what i think.
I successfully wired my edis up the first time so order ACB is confirmed.

Thanks for all the replies so far everyone!
I've just nipped into the garage and in this pic:
The little connector with 1 2 3 4 on it I've just realised I've got wired incorrectly. In the diagram where 4 is the earth/ground I have
that as a coil and I have pin 1 as the ground. But pin 4 is thicker wire, and 1,2 &3 are all the same thickness :/ why is that? How would this
effect the ignition etc? I'm off for sunday dinner now so I can't look at it again for a couple of hours!

No earth for the coil, it goes to positive supply. Connecting to earh gives no output.

One thing to bear in mind - as long as the cylinder pairings are correct , the actual firing order is irrelevant
And as has been said - there is no earth on the coil , just three inputs from the Edis and a `switched 12v` from the ignition .
Its cuz I is blond , innit

Ok ignore that 
but according to the diagram I haven't wired it up right.
Note the big and the small tabs on this connector
According to the tabs (and this is the same on another diagram I've seen) I have it the wrong way round. So I have the switched live going to
pin 1 and pins 2,3 & 4 going to the coils. I'm still getting sparks, i think on all plugs... so will the coil order be messed up
because of this connector's wiring?

Yep!
Do a bit of cut and shut on the wiring and make sure to use the capacitor off 4 to ground... (shown at the edge of your piccy)
