Das habe ich schonmal gemacht, dazu zitiere ich mal den entsprechenden TB-Post (

Humbucker
Orange + Blue = connect
Green = Hot
Shield/GND = braided wire
Single Coil
Orange + Yellow = connect
White = Hot
Shield/GND = braided wire
What you need is to connect the orange lead from the main coil (C2) with the blue lead of the humbucker coil (C1), and the green lead will be the output. Use it as a pair with the shield lead. And don't forget the red lead goes to the battery bus. Notice that you don't need to use the yellow and white leads since these are the dummy coil's (C3).
if you'd like to use the TW pickup as permanent J pickup instead, then you'd need connect the orange lead with the yellow lead, and the output will be the white lead. Also use it as a pair with the shield lead.
