Hey guys,
If it's the "Special", I've noticed that it comes with a pair of leads. One hot and one ground.
To easily establish if it's so, open the back cover, there'll be two sets or wires from the pickups appearing from cavity in the wood.
One type comes with red housing or blue housing with a white inner core/ bare wire on the outer core. This is the single conductor with ground only. This cannot be coil split without it being dissected and rewired.
The other comes with generally a black housing with a bunch of five wires within it. (Eg red,black, white, green, bare)
This has the ability to be split as it has the option of breaking the continuity of the output from both the slug pole pickup and the screw pole pickup. This is the four conductor type with ground.
As per what jcvw75 has said. You can refer to the schematics provided online by Seymour Duncan's online site. There are colour code variances between the different brands of pickups.
Anyway best wishes...
Hope the coil split thing works out well...
Happy Diwali...
