Not sure how to wire

    I have a Squire Affinity jazz five string bass. I recently picked up cheap a DiMarzio ultra five neck pickup and want to replace the stock Neck pickup on my bass. I know the original pickups are single coil and this new one is a split coil pickup. Is there a way I can wire this split coil Neck pickup into my bass so that it will play nicely with the original single coil Bridge pickup? The original pickup has one black wire and one white wire. The DiMarzio split coil pickup has one green, one red and one grey wire. Thanks for any suggestions.

    The first thing to do is check that it will fit in the pickup cavity.
    It's been mentioned more than a couple of time on here that DiMarzio 5-string pickups won't fit in a Fender/Squier.

    You're going to have a problem with the bridge pickup being noisy after the change, because there's an odd amount of coils (3).

    Normally the Jazz pickups are set up with one reverse wound, reverse polarity from the other so that they cancel hum when both pickups are selected.
    This feature would be removed with a humbucker in the neck. Sure the neck pickup will cancel hum when soloed, but when using both pickups the bridge pickup will likely exhibit single-coil noise.

    Unless you were to figure which coil of the DiMarzio humbucker is reverse wound, reverse polarity to your current bridge pickup.
    One option is to wire in a push/pull pot that switches the DiMarzio to single coil mode, thus allowing it to hum-cancel when used in conjunction with the bridge pickup.

    While you have it open go ahead & replace all the pots with 500K Ohm values.
    Unless you don't like the extra brightness & output, in that case keep the 250K Ohm pots.

    How will I know if it is out of phase?

    It will sound thin and honky. It should be pretty obvious.

    Already have the fit taken care of. The noisy bridge pickup is the problem. Maybe i will have to replace the bridge pickup with a bridge DiMarzio pickup as well to get the full benefit without the noise. I will look for another used deal for the bridge.

    Here's a description of how to check polarity:

    In your case black & grey are combined, so:

    Check the polarity of grey to red (grey on common lead of multimeter)
    and green to grey (green on common)

    compare that to your existing pickup & choose accordingly

    Like I said this DiMarzio pickup only has three wires as is shown in the PDFs that slater posted, by the way thanks slater, that is how I have it wired. I guess the answer is another DiMarzio for the bridge.

    I just told you the answer :wideyed:
    in a 3-wire setup the black & grey have been combined
    you can still do parallel/series wiring or coil-splitting

    Getting pretty tired of trying to help out & getting snubbed.
