Do me a favor and start a new thread on that. Put it into the Electrical board. Document it as much as you can. I can tell you though from others doing that there's not a lot of room behind that plug.

O.K will do,started into it today, took off the screen, infill panels etc but ran into a spot of bother.
What a bugger, there's a mounting bracket type deal directly behind that round "Blanking Plate" on the left hand side of the dash, just to the left of the headlight adjuster knob.
Can't get to the back of it without further, more involved dismantling.
Hmmm, time for plan B.
I'll do a write up with pics etc and put it in the suggested board.
Just have to come up with a cunning plan first,,,
