What is this plug on the under dash panel for? Is it to do with climate control?

Is it a "bong bong bong" thing for when you open the door with the keys / lights on?

Edit.. nope...that's the other thing pictured. Sorry.

I don't think so, it looks pretty original as does the wiring. My money's on something to do with the climate control but confirmation would be nice.

i'm sure my early prefacelift SE had this and it had something to do with automatic head light adjusters, possibly.

I don't think so as it has a plug and wires and the headlight adjustment is purely hydraulic.

It is indeed to do with the early climate control system.

I think, it's temperature sensor for car with automatic temperature regulation..
