Rooster, the early UK Soups (like mine ) had a "false" third brake light!!! The loom connector you pointed out goes from in the boot to the panel just behind the passenger seatbelt. It will clip onto a brake light if you buy one from toyota (about 90quid). Here is where I connected a cable to it and attached it to the brake light circuit in the boot. You can get a piece of wiring loom to match this all up but it was v. expensive (compared to a bit cable and some solder and shrink tube). But at least if you use this it takes away the hassle of runing cable up the hatch.
Hope this helps.
God only knows why they didnt just put the 'real' one in
