Adding a 4th SCV

[zuiko]

I have 3 SCVs right now, two on the loader stick and one on another valve.

What would I need to do to get a 4th SCV for use in the rear? The power beyond kit + a two axis control valve to replace the single axis one?

Anything special I need to watch out for on buying a new valve (normally open/closed? size?).

Do I just connect the power beyond kit to the extra outlets on the new valve or do I have to do anything else?

Thanks!
