Er....whats this wire for???

[Damo]

Hi,

Just literally ripped the crummy old Clarion CD player someone left in a 2001 Seicento Sporting (the cage was jammed so it was a near "prise it out" situation). Just noticed amongst the wiring one plug that was'nt connected to the stereo. Its a small black female plug with two small connectors in it and only one wired to a red/yellow cable. Any ideas what this is for????

Has it been dislodged from something?

Eeekk! Got a new Sony Xplod CD receiver coming and I don't wanna break anything.

Thanks,

Damo
