Installed my auxiliary shelf this weekend with power socket, Datel voltmeter and driving light switch. Had an extra hole for a future switch and decided to put in a panel mount fuse for the lights and socket. If you didn't know better, you would think it was from the factory. Very pleased. One installation tip is to route the wiring back through the forks before going to different points on the bike - that seems to reduce the movement of the wiring at the shelf, and therefore the wires rubbing on on other parts.
