Green 2 pin plug goes where?

[Littledigger]

I've just removed the inlet manifold on my clk 270 cdi (pre facelift) to remove the swirl flaps and after re installing the manifold and stuffed the wires through the middle, I have a green 2 pin plug that I can't remember where it plugs into. It's on a short wish wire but just can't find where it plugs into. I've connected the sump sensor, the starter wire, the top of gear box plug (crank sensor I think) but at a loss to where this 2 pin plug goes. does anyone have a sensor diagram?

SOLVED. Still don't know what it connects to but I solved the problem by getting under the car and reaching up above the starter to have a feel. found the socket for the plug.
