Bongo Fury

Hi all,
We've had our beautifull Sparklebucket for a week and a half now and she's a bute (2.5td, 2wd)!! However, we have found an unexplained wire under the bonnet (we know that the previous Japanese owner installed all sorts of techie stuff that was removed before it was exported). As a curious couple, unexplained wiring drives us nuts - so if you can help us get a good nights sleep and teach us a little more about our latest addition it would be greatly appreciate it??
Many thanks for your help and below is a photo.

If its any comfort it exists on our V6 as well, I can't make out which connector it is on the wiring diagrams, it seems to be coming out of the "B" or "F" wiring loom, but there doesn't appear to be a 3 pole connector with Black, White and Green wires shown, but I am probably just missing it at the moment!
