Re: 2 conductor pups. JP wiring or similar?
Nope. With 2 conductor humbuckers the coils will be internally connected in series. If by chance you have a start, finish, and a separate baseplate ground you could reverse phase or add a switch so that both pickups are on in series. If it's the more traditional single conductor with the braided shield then there are very limited switching options, short of modifying the pickups.

Re: 2 conductor pups. JP wiring or similar?
Your PU's are actually single conductor with ground. Fear not, you can still do some things with push-pulls. One is phase, that reverses polarity of the magnets & gives a hollow, warbled sound. You can hear it on various albums.
Another is linking the PU's together in parallel to series, directing the current into one PU then the other. Within two coils, this is known as "humbucker" mode, and it gives an equal boost in volume & mids for linking two separate PU's (doesn't matter if they're single or double coil). This is half of the Jimmy Page system (the other part is coil cuts for the two HB's, which you need multi-lead PU's for).
When you have two HB's in series, they're darker as treble is reduced. Where the parallel/series link between PU's is the most useful is when one PU is a single coil (or a HB in coil cut), or when the PU's are in phase. Parallel/series is especially good combined with phase is it fills in the drop in low end and volume which normally happens with phase. It's a popular option on this forum.
Check ot the diagrams on this site, they're excellent. If you need something outside of that, Artie is the man.

Re: 2 conductor pups. JP wiring or similar?
ok, so I can do some things...
I am good at setting up circuits... if I am given a schematic, I can do it. I couldn't find any schematics with 2 conductor pups in the SD site though...
Mike, is the finish lead easily accessible? I wax potted my pups (and it came out quite thick) can I dig it out?
blueman, Do you have links to any schematics I can use?

Re: 2 conductor pups. JP wiring or similar?
No you don't. I've done phase & PU's in series with only a hot & a ground. You don't need more than that.
With Duncan's, the white & red are sometimes connected & taped together, so in some of the diagrams they're really only using a hot & a ground. You need multi-lead PU's to do coil cuts (single coil) & coils in parallel, so that the coils can be isolated are handled differently.
With phase, you're just switching hot (black) & ground (green) to reverse polarity via a push-pull. And with the PU's linked in series/parallel, you're dealing with an entire PU, not individual coils, so again a hot & a ground are all you need.
If you look at a diagram of the 4 push-pull Jimmy Page system, and eliminate the push-pulls for coil cuts and use regular volume pots, one tone pot does phase, the other tone does series/parallel. So you can use that on any guitar with two PU's that only have a single lead and a ground.

Re: 2 conductor pups. JP wiring or similar?
Still, I can't figure it out from the existing JP schematic in the site...
btw when we say series/parallel, we are only talking about the the two inner single coils of the two humbuckers either being in series or in parallel when the three-way is in the middle right?

Re: 2 conductor pups. JP wiring or similar?
Thanks a lot hermetico. As soon as I get the push/pulls, I will let you know if it worked out as it should. I appreciate your help and your time!
btw, in your diagram which color wire is the inner pup wire and which one is the outer wire?
on the bridge volume pot, is there a connection on the pot (it seems to be touching but there is no dot)
also, which color is the inner jack wire and the outer jack wire.
Yeah, I need instructions to be clear

Re: 2 conductor pups. JP wiring or similar?
I phrased the question wrongly, I am sorry.
I have the old style wires on my pups. The wires are a wire mesh on the outside and a wire on the inside insulated by cloth.
Like this: http://www.mojomusicalsupply.com/item.asp?pid=65795&pg=13809&id=2112015
and I am asking which one is the blue and which one is the black wire...

Thanks Robert.
and the jack, what goes to the inner tip and what goes to the outer tip?

Re: 2 conductor pups. JP wiring or similar?
Technically you don't, however you deserve every bit of noise that you get when you pass the "hot" side of the signal through an unshielded conductor. It also places the baseplate and consequently the poles (and a cover, if it's there) in the circuit.
Additionally, passing the signal through an exposed conductor is asking for shorts. So can you do it with a single conductor with a braided shield/ground... yes. Is it good practice... no way. That's all I was saying.
