Having just got my first Z, I've got plenty of questions, most of which get answered with a bit of searching. This ones really odd ball though.
So, at some point in my Z's life it was stolen. The original ignition was trashed and replaced. I think they put in the wrong one. The steering column cover doesn't fit right and you have to get behind the combo switch to get the key in.
I know this is in interiors, but I figured I'd mention that it's got a couple black wires with male spade terminals dangling too.
