4 conductor humbuckers can be wired pretty much the same as single conductor
All you have to do is solder the South of the 2 coils together. In the case of Dimarzio, you solder Black and White together, and just tape it up. You then solder Red to Hot, and Green+Bare to Ground.
If you have Duncans, the color codes are different. Every brand is different so CHECK THE COLOR CODE FIRST!!
