Swanpyankee, You will be needing a 2 way, single spool valve with a power beyond sleeve. You will have to take your power off from the power beyond port on your loader valve. and then feed your 3 point hitch from the power beyond sleeve on your grapple valve. Being I am not real computer savy, give me a call at 585-343-0770 and I will go over it in detail with you. Please call me before you try to do this because you can do some very costly damage if it is hooked up wrong.
