"spare" connector in engine bay

[pauljsgreen]

just cleaned the throttle body, etc and used some spray degreaser to try and make things look a little better under there.

please be assured - i gently rinsed the engine - no spray or pressure washer!!

however, while putting everything back together, i discovered this spare connector on the RHS under the intake manifold and near the engine bay cooling fan.

i can't find anything obvious that it has come off of - maybe it's provision for an option i don't have.

anyone got any ideas?


many thanks in advance
thanks
paul
