Where's my stereo wiring plug??
 

Hi all. I took my dashboard out a couple of weeks ago. Putting it back together now and I have every plug accounted for except for one.

I can't remember if it had one in it previously or not?

It's a 2005 231 6 speed with head up display and dvd player in the rear compartment...

Please help !
