wait a sec.
take a deep breath, whip out the multimeter, paper and pencil, and hear me/us out.
first of all, draw on a piece of paper a schematic version of the switch. all the terminals, what goes what, and colorcodes of the pickups.
you see that the pickup has some colored wires together at some spot, and then some other colored wires at some other places. I don't have my glasses right now (and the pic is a bit too blurry) so I can't tell what goes where. but you can, so: write it down!
then, desolder all the leads of one pickup. use the multimeter to see what connects to what. Green goes with...? red? black? white goes to...?what?
you see that 2 wires going from the pickup soldered together are on the switch. I can assume with an educated guess that that spot is for the coiltap.
so, solder the duncans exactly the same way! red/white goes on spot where the green/white is right now (at least, I assume it's green/white, I just can't see it that well). earth to earth, etc etc.
just copy and paste! uhm... solder.
it aint that hard.
