Hey,
After doing my own research, i've decided that i'm not good at researching and asking is easier and more effective. So....

Been ebaying, bought 2 humbuckers (dimarzio dual sound and evans eliminator 2 rythmn - any feedback on the evans is appreciated, couldn't find that much about them, but apparently they're amazing?) and 4 pots destined for an old les paul copy i acquired...

The pots supposedly originally came with some emgs and were surplus - hence sale. They are wired together in a chain, but non of the wiring diagrams i've looked at seem to match this arrangement. I also don't know which is intended for tone and which for vol, i think i do, but im unsure.
-They are in 2 pairs connected via a ground wire.
-Each pair has one pot labelled A500k and one B500K
-The A500k have 223 resistors(?) between 2nd terminal and ground. I think this is the tone pot....
-The B500k pots have terminal 1 grounded and the 3 terminal wired to the 1st of the A500k

Why are the wires and resistor as they are - i'm yet to see a pic with this format. Can i just take it apart and use either pot as a tone or vol?

Any explainations much appreciated, and i'll be back with more wiring dilemmas in the future i'm sure...

The 500K means that the resistance between the end terminals is 500,000 Ohms. The A & B designate the amount of change in resistance value at the centre terminal relative to the motion of the shaft. Don't worry about it; just be aware that they are different.

That 'resistor' is actually a capacitor. The 223 means 22,000 pF (pico Farad) or 22 nF (nano Farad). So that is the Tone pot.

I don't know about the Evans, but those values should work OK for the Dual Sound. Check out DiMarzio to see how to wire them up.
