Nik is absolutely right Ben! The head unit and aircon are connected by one bracket (the screws on the side of mine were stripped as s#!t). I got mine out without touching the DIN gauges.

Whatever you do, ground it right behind the shifter! Let me know how it goes, because the wiring on my Pioneer were completely different than the Skyline's. There are plenty of things that don't work now, i.e. subwoofer, rear speakers, cd changer.... :oops: ...hey, I'm not an electrician! :lol:
