    Hello to everbody, I'm new here...

    I exchanged the Dragon II's in my '99 PRS for two SD's.
    So far.
    Now the wiring... I'm confused and can't get it right.
    I prefer a wiring witout having to flip the magnet.
    I have the 5-way rotary switch (latest version) in my PRS.
    Could anybody pass my a diagram, I can't find anything suitable.
    The diagram on the Seymour D website shows a different switch.

    Maybe even sent me a digital photograph of the electronic compartment of someone who's got it done right?

    I hope you can help me out. Greetings Ruezzz from Holland

    First of all... which two Duncans are you using? Does either have multi-conductor wiring?

    A PAF 59 > Bridge / Alnico Pro II > Neck
    Both with four conductors...

    The problem is the rotaryswitch and having a to flip a magnet (or not) I guess... You get me? ;)

    If the SDs are not covered, flipping the magnet is the best way to do it, seriously. It's not hard - just remove (or loosen, often) the four brass screws in the pickup base, slide the magnet out lengthways, flip it, reinsert it and put the screws back. No major surgery required.

    If you don't, the three middle positions of the rotary will not be hum-cancelling, which is a major point of that system.

    If you do flip the magnet, everything works as intended and wiring is straightforward too.

    (When flipping the magnet, turn it either along its length or across its width, but not both, or you'll be back where you started! You only need to do one pickup of course.)

    Once you've done that, the wiring corresponds simply: SD green = PRS black; SD black = PRS white; SD red/white together = PRS red. (I could have the green/black the wrong way round, Jim Collins will know :) - you'll get the wrong coils in the three middle positions. If so, exchange the green and black wires on each pickup.)

    I've used Duncans in all of my PRS guitars - four in all. My first two PRS' - an '89 and a '90 Custom - didn't require flipping a magnet. Granted, the mechanics of the rotary switch have changed since those guitars, so I'm talking a bit 'out of school' for your '99.

    I'm not Jim Collins but I also know ;) , you got it right.

    There is an alternative if you really don't want to flip one of the magnets: simply turn one of the SDs around 180 degrees (if you don't mind the lettering upside down). The connections would be:

    If you turn the neck SD around:

    Neck:
    SD green = PRS white
    SD red/white = PRS red
    SD black = PRS black

    Bridge:
    SD green = PRS black
    SD red/white = PRS red
    SD black = PRS white

    If you turn the SD bridge around:

    Neck:
    SD green = PRS black
    SD red/white = PRS red
    SD black = PRS white

    Bridge:
    SD green = PRS white
    SD red/white = PRS red
    SD black = PRS black

    I did it!!!

    Thanx again y'all. You ROCK!!!
    I flipped the Alnico's Magnet and used the right colorschedule.
    30 minutes of effort...

    My problem seemed to be that I started of wrong with totally incorrect information given to me by a dutch guitarshop...

    Soundimprovement? Certainly!!!
    That's more my taste anyway.

    Thanx again!
