anyone know what this plug is for ?

[Milby]

was looking behind my dash because i got bored and on the plug that goes into the headlight switch there is a red plug not being used (see picture) just owndered what's it for and should i plug it in to something 

[Len]

Probably fogs.

Depends what car you got.

1.4 se had it don't have fogs :S or the wiring for it as far as i know i want fogs and planning to fit them hence why I had a quick look at the loom for headlights

[Len]

Wiring looms can have all sorts of plugs etc. with nowhere to go.

I'm only guessing as I'm sure my headlight switch has that secondary plug.

i was thinking it had no purpose

I think its for electric headlight height adjustment. Some cars have the loom, but none of the other bits needed to utilise it.

Edit: trog_nfs beat me to it

(I think this might be the height adjustments on headlights?)

[Milby]

thinking about it now it sounds like a pretty good answer

^^ As above

It's defiantly the headlight level wiring plug.....
