Whilst sorting out my blower motor issue I came across a loose wire in the scuttle in my car (2005 D3) which looks like it's for a heated screen, but it's gaffa taped to the loom and doesn't have anywhere to plug into.

Can anyone verify if this is a heated screen wire?
Does this mean I've got a heated screen fitted, but the car doesn't have the loom for it?
thanks,
James
