Wiring Guide.

Bolt on if you want to add to existing printed part or built in if you haven't printed it yet.

Bolt on version will require an M3 x 12 or 14mm long nema screw and if you lay the part with the big hole down, it will be stronger than the integrated version. This along with Coolreactions http://www.thingiverse.com/thing:783678 cap should make for a nice install.

P.S. Why is every one installing the motors with the wires comming out the side and not up?
