All I can make out in the picture is some pipes, how many spools have you in the loader valve,if its a two spool you will need another valve for the grapple,to plumb that in remove the return line from the loader valve,put a high pressure hose from that port on the L/valve to the grapple valve in port, from the G/valve out port connect it to the return line and then two lines to work the grapple, the circuit has to be from the pump through the loader valve to the grapple valve and back to the reservoir,the loader valve will have priority over the grapple,if there is a three spool loader valve all you should have to do is attach the grapple lines.if you have to get a valve get one that's the same or bigger but not smaller as it would restrict the oil flow,
