I know this isn't a John Deere part and don't know how it would affect warranty, but W.R. Long makes kits that include all you need to add a true electric over hydraulic valve control for a grapple or 4 in 1 bucket. You can search WRLong and find their site and number, where they show their products. Talk to Nelson (who I assume is the owner) who can advise you. I purchased this kit for my Kubota and my dealer installed it. I don't see why it would affect a warranty. I have been very happy with mine.
