I think the 4 way connector from here should fit (can't be sure though)

Make sure you buy the terminals to go in the connector too.
Getting back to the subject, I set the TPS to 0.340v this evening and went out for a ride. The bike still made 5 bars on the RID and it was about 45 miles when the first fuel bar disappeared. I didn't fill the bike back up again so I can't tell what the actual fuel consumption is yet. The bike rides well, with no real noticeable surging low down. It pulls well and is steady at motorway speeds. The plugs now have a noticeable light tan colouring on the insulators and a full turn of soot on the base ring (I tried to take some photos but they didn't come out too well).
