Honestly, shortening and making the reciever wires black is something I always do, just run the risk with warranty (so far, I've not had any issues from that, except when I reverse connected one... my bad!). With the V3, it's actually a lot easier to do, as the case uses four screws (rather the two and two clips of a 2.1), and the wire connections are easily accessible on the board.
Again though, do it at your own risk..
