EHV 3rd Function orifice?

I am gearing up to install a grapple and I am going the 3rd function route instead of a diverter so I can have another outlet available for an unknown future attachment. I plan on tying in at the power beyond. Will I need an orifice or two somewhere? I am assuming it (or they ) will need to be on the work ports either right at the valve exit or maybe up on the loader at the bulkhead where the grapple connects.

Thanks
