I have T2s on order so I'll be dealing with this soon too. When I had my Raptor, which is an almost identical setup, I drilled a hole in the plastic on the side, near where the front, lower part of the tank is. On the Raptor there was enough room for the ignition to fit in there. I used a holesaw to make the hole. Some people installed the idiot lights into the top of that front cowl that the Raptor has. I know the Z doesn't have a separate front piece but I think it would work just as well, as long as there are connectors so you can remove the front plastic easily.
