This is the connector on my 2011 Tenere - it's behind the plastic cover under the clocks.
I used some crimp on 2.8mm male blades inserted into the connector with heatshrink to insulate then connected to a relay to feed a 12v DIN socket, GPS, a charge state LED and a spare for heated grips at a later date. Nicely fitted into the plastic backsides of the grey upper tank plastic bits.
I should take a picture of the neat and tidy job I made of it!
I got the connectors (and other bits) from these people:
