Righto, i've got an xh, just bought a new head unit off a mate. he had it in his el and is leaving me with the stero plug coz he's selling the car..
i know this is gonna make me sound like a noob but i'll be honest i know bloody nothing about the audio side of things, but will this plug fit into the xh socket??

The XH should be the same as the EF/L Already...

It is.
