You've got all the gear you need there. Just connect the two ring terminals up to the battery.

BTW the alternator on the Z will not cope with an additional 30A draw! Of course you are highly unlikely to be using all the sockets and anything like that in normal use, but to be on the safe side, I would change the fuse that's on the orange wire to a 15A. This will be more than amble for most heated kit, chargers, satnav etc. and save you inadvertantly frying the stator, reg/rec unit or starting a fire!
