    your pickup appears to only have 2 leads

    Usually the small rail type pickups have 4 leads coming off the bobbins, I only see red and white on your pickup, so maybe that's all there is , that and the bare ground wire.
    If that is the case one of the two / red or white, is hot.

    Most pickup manufacturers use the same four colors (red, white, green, and black), but there is no industry standard as to which color is used for what. The rails pickup in the picture is definitely a two conductor (you can tell by the empty holes on each side of the baseplate where the other two leads would go if it were a four conductor).

    The part that complicates this is that in typical four conductor Duncans, the red and white leads are attached to different coils (they're the two that get taped together when converting a Duncan four conductor to a two conductor wiring scheme), so this makes it a bit more difficult. I would just wire it one way, and if it ends up being out of phase with the other pickup simply reverse the red and white. The bare wire is connected at the same point as whichever one winds up being the ground lead.

    Thanks Frodebro, the part that is confusing is that its a older Seymour Duncan Hot Rail.I also have another older hot rail that looks exactly the same but has the ground wire.

    So it is already wired in series aka hum bucking mode. 4 conductor allows for other options, parallel, coil split. Which most folks don't use anyway.
