A doozy of a question re identifying this...
Hi All,
So in the process of doing work on my car (it's gone a lot more involved than planned) I had the windscreen removed to check the surrounds for rust and re-do the seal.
Now while looking around I found this (see pictures - one is with plug removed and other with plug on) just under the windscreen with the plastic cowl/louvre removed pretty much in the centre. Now obviously by design (mounting etc) its factory. I haven't delved behind the dash to see where it goes and I have a slight suspicion what it might be. Also the service manual doesn't seem to help.
Look forward to an MR2 nerd telling me conclusively...
