Can anyone identify this wire? Ibiza Cupra 2.016V

[italian job]

Just finished putting my ABF engined Ibiza back together after a clutch change,to do this i removed the front bumper/slam panel/radiator as well as starter motor.Its all gone back together nicely and everything works as it should as far as i can tell,my only warning light is the airbag warning but i'm thinking that needs turning off with vag com (i removed the steering wheel/airbag as i changed the steering column)
I'm left with a single black wire with a red female connector,it disapears into the loom near to the starter,i have pulled it up for the photo,could it be redundant on my car as it doesn't have aircon? Just a thought.

Thanks for looking.

Cheers Paul.

was always one wire that everyone decided did nothing that used to lie across the front of the block even with AC but ill check in mine later and make sure it was black with red connector

dont ask me why though but ill double check later

The immediate things that come to mind are horn, ambient temperature sensor, but if they all work then maybe its one of those extra unneeded wires!

Thanks for both replies,the horn wasn't dis connected and still works,the ambient temp sensor was disconnected but was re connected and is working fine,cheers for the help.

popular opinion decided it was commonly unused and apparently somethign to do with an accessory gauge connection

I'm trying to think back to my KR 16v engine. I have a feeling that there was a cable that connected somewhere on the top of the bell housing on the gearbox near where the cable went in for the rev counter/worm drive. Maybe I'm dreaming as it was 10+ years ago.

Wouldn't be a rad temp sensor wire to switch the fan on when it overheats?

its the oem gauge sender unit plug..will do nothing unles you have the gauges
