Unknown contact on harness by the 'data tag'

[scotty]

I've got an unknown contact just to the left of the 'data tag'. It's a white contact with two connections. You can see what I mean by 'data tag' here: http://www.ma70.com/bishop92t/techtips/7mlayout.jpg

If wanted I can take a picture of it.

Thanks,
Scott

do you have the alarm horn, to the right of the tag?

Nope, got no stock alarm horn.

Pic of the engine bay, old pic, but most is the same layout. http://www.mitoforum.org/priv/supra/worklog/172.jpg
You can see the cable just to the left of the data tag there. Please don't mind it being extended, that's just me messing about.

Found a pic where you can see the plug also, http://www.mitoforum.org/priv/supra/worklog/188.jpg, white connector right about the "supra turbo" inlet pipe.

It was for the alarm you can see it well here. Its probably there so toyota didnt have to make two different harnesses for with and without alarm.
