Pickup question on PC1/Collen guitar

[Ram Air Intake]

Hi I was considering changing the pickups in my Jackson DK2S, to match the PC1s pickup configuration. I have the Super 3 Laying around and I will have to get a hold of an HS-2. Here's the question does anyone here have a diagram or a PC1 that are able to tell me how the middle pickup is wired, in humbucking or split type single coil. Any input is appreciated, thanks.
