what is the OEM connection to the socket?
can this be a direct swap or do you have to modify the wire harness / route to the battery?
The usb socket I linked to in post #4 is a standard 30mm diameter socket; drops right in the OEM socket hole in the dashboard with no modification, and has a backing nut that secures it as tight as the oem socket. It has waterproof spade connectors to the socket and eyelets on the other end. The OEM connector is a JIS(?) standard 2 gang type. It is switched; only powered with the ignition on. If I was going to wire it to the bike's wiring, I would cut both the bike's connector and the usb's eyelets and install the same type of waterproof male-female spade connectors. That way you can disconnect it easily to remove the dashboard.
But I didn't do that.
I simply taped off the OEM lead, connector and all, and ran wire from the dual usb socket, which came with about 3ft of lead with an inline 3a glass fuse and eyelets. I cut those off (incl the 3a fuse) to add wire to route it to the tail section where I installed my fuse block,
* then soldered new eyelets on to connect to the block, and protected it with a 3a ATC blade-type fuse. This way I can have the usb's unswitched as the socket has its own touch on/off button. I can power accessories and chargers with the ignition off, and have the ability to turn off power to the usb hub when not in use (it has leds in it that glow when on).
*I connected the fuse block to the battery with 10ga AWG primary wire.
