If I'm not mistaken, you would only need to wire 19 signal terminals as the headlight, remote and mute wouldn't be of much use in a home docking bay. And wouldn't it be easier to wire a power adapter to the in home power connector istead of wiring the ground and I would assume that you would need to split the hot to the permanent power and the ignition switch to get the empeg to turn on? So then you would only need 18 signal and no power terminals.

Someone correct me if I'm wrong.
