Looking to purchase Yanmar SA 324, add 3rd function,grapple

[shiftsuper175607]

I want to add a 3rd Function valve for a grapple.

At the dealer I am not able to see the loader valve.

Does it have 7 lines on it? As in...does it have power beyond or is the loader end-of-the-line.

The dealer said he would add the backhoe function PB for $300

I would rather go straight to the 3rd function valve from the loader valve. (save $300)

The bucket has an odd connection...not skid steer so need special made grapple ($1250) or adapter to skid steer$.

Any help would be appreciated.
