The Dealer installed the third valve kit and lines..... I then added the quick couples for the attachment itself then zip tied it all back in place. I can drop the grapple and switch to bucket , forks, etc.The Grapple and Third valve cost me $2,500 installed. The lines are run from the rear mounted remote valves, I also have an extra set of couplings in the rear available.They also put in both control levers. I can also drop the loader because they installed an inline set right above the hyd manifold for the loader. No need for an restrictor, the valve runs the grapple just fine. Plenty of control. Grapple may be a little light for some uses but with care its a good unit. The bottom tines CAN be bent by heavy rocks, etc.
