Pinball

Hi. I have just purchased an X2 (F39) that was stolen/recovered in Japan. When it arrived here I found that the HU had been removed, so I purchased a HU NBT second hand. The HU NBT now needs to be setup on the vehicle. I can do basic stuff via e-sys but am a bit out of my depth with getting this working. Help! Can someone please point me in the right direction to get it up an running. I really don't know where to start. Thanks
