Yup, that's exactly what I mean. The one I have has the two holes for the two white prongs. As I said, I will double check the model number tomorrow. The main issue that most people have with the boss is that they get one with the spots for HICAS prongs in the wrong place (6 and 12 oclock off the top of my head).
Regardless, just don't actually expect your HICAS to work properly: the system doesn't seem to like old age
When you take the wheel off (if you haven't already) make sure you mark exactly how the HICAS disc lines up with the spline. A liquid paper pen is quite useful. Oh, and getting the OEM wheel off can be an absolute bitch: make sure you keep the nut on the spline so when you whack the wheel off it doesn't fly into your face.
Again, interested to see how you plan to integrate the LCD...
Edit: if you do **** up the alignment of the HICAS ring with the centre spline, use the OEM wheel to line it back up. There is a dot on the wheel that matches one on the spline IIRC.
