Not that terribly hard to get ahold of actually but they aren't cheap especially when no one I have seen yet can rig them to work...at all or like they are supposed to.

I can't remember who it was that got one but someone on this board had one...but that was a while back.

From what I know its a real bitch wiring it in since in the JDM cars the wiring color codes is different and there are added sensors for the unit and some othe stuff along the way.
