Hey guys!

I have a little problem.
I purchased a Dimarzio Crunch Lab and I'm about to install it.
The Cort X6 I install in has stock pickups yet, a volume knob, a tone knob push-pull(coil tap) and a 5-way selector (neck, neck coil&middle, middle, middle&bridge coil, bridge).
It looks like this:
As you can see, the green bunch is the bridge's.
The electronics looks like this:
As you can see, the green cable divides into a red, a white and a black. The red goes to the 3rd plate from the left, a white to the last and the single black must be the ground, it leads to the volume knob's ground.

The dimarzio's cable looks like this:
It has a green cable as well.

How should I install? should I just replace the pickup like where the red lead solder the red, where the white lead solder the white, solder the black where the black lead and also solder the green to that ground?
I don't really understand the instructions, it said many things and I don't really know what to think.
The instructions:
Should I listen to the general instructions? I've watched several wiring diagrams but I don't really understand them.

Please help me with this to be installed!
