No need to cross-post the same question to multiple forums - We'll see it :)

Right, um.... this could be a tricky question! Just checked the service manual and I can't see a diagram showing the lead connection points... What I can tell you is that the firing order on the V6 is 1-2-3-4-5-6, so as soon as you've found where cylinder 1 is on the dizzy, the rest should follow. I think the cylinders are numbered as follows, as you look in the engine bay:

1 2 3
4 5 6

But I might be wrong on that. As for where to start with the dizzy - Is there a marking showing the cylinder numbers or at least the first one?

Yep, that's right - Numbered as you look into the engine bay from the front.

dizzy starts 1 at 5 o clock then goes anti clockwise to 6, wont start so i take it the cylinder numbering is wrong or the new ht leads i have are **** lol

so then it must mean

456
123

surely the length of the leads are a clue?

I'm sure I've seen the V6 layout posted recently as

456
123

also.

Not sure the lead length would help though Mike? Well, not if they're completely detached!

yea the leads i have are blue print and are longer than the old ones.

ill try it that way and see what happens, ive done a big service so i took everything off then realised i should of really wrote the lead positions down lol

Maybe some kind soul with a V6 could take a look under their bonnet and make a quick note of which leads go where? I would, but alas, my V6 has moved on to pastures new...

I checked on my V6 (previously Nev's ;)) this weekend, and the results are as follows:


The cylinders on the V6 are as such (when looking from the front of the car):

135
246

And the firing order is indeed 1 2 3 4 5 6

The distributer goes anti-clockwise, with #1 at 5 o'clock... the distributer cap actually has the cylinder numbers marked on it! ;)

Yeah Confused is right, if you think about it logically, a wasted spark system as on the VR-4 would never work with 123 all being on one bank.
