As soon as the UPS delivery arrives, I will be ready to start installing my front SCV for a grapple and snow plow. I will be using a Northman 12 gpm valve plumbed into the power beyond port of my JD 4510. Because the hose and tube kit for my 460 loader is no longer available, I am going to use the BW16139 kit from a 400x loader, which the dealer said will fit my 460 "with some minor adjustments." I will either use a Scorpion S-Series grip, or fab one of my own. My question is: How do I wire it up? Does anyone have wiring instructions or a wiring diagram that shows how and where I attach which wires between the grip and the valve and to the load center?

You just need to provide momentary power to one coil at time to operate the valve, so to answer your question we'd need to know what switch options you are getting in the handle, and what they are rated for (current wise), that will determine if you need relays or not.

I have decided to fab my own handle. I plan to use a [email protected] three position, spring return to center rocker switch with momentary on - off - momentary on. The led indicator lights on the switch are just for show. I understand that using a [email protected] switch, I won't need a relay. Will that work? If so, is there a wiring diagram you might be able to share?

Just google a diagram for a DPDT or SPDT switch.
Basically supply power on the center terminal (3A in your picture), then each outside terminal (2A and 4A) will go to one coil. If the grapple doesn't open/close as expected-just reverse the outside terminal wires.

Where do I get the power? I assume it should be fused, right? Is there a specific terminal or fuse slot in the load center I should use?

I can't get that specific, sorry-I just don't know your machine well enough, but yes of course any new circuit added should be fused.


Not saying this to offend you, but if you don't know how to do basic wiring like this, you may want to rethink this project. Doing the hydraulics will be harder than the wiring.

Well, to date I have found this site to be very informative, with all sorts of people asking all sorts of newbie questions and receiving measured and mentoring assistance. I can't recall anyone ever discouraging them from undertaking a project like this. I do indeed understand basic wiring and have wired up everything from houses to theaters to factories to cars and trucks. None of that experience, however, informs me as to which specific terminal or fuse slot in the load center I should use to power a new SCV on a John Deere tractor. My hope in posting on this site was that someone who has experience specifically with John Deere tractors might venture to help me with an answer or a citation to a JD schematic or wiring diagram as I have seen countless times on this site -- to questions objectively a lot dumber than mine.

I did the same type mod. I do recommend the scorpion Joystick. I believe you would be very happy with it. In the post i wrote up i did make a picture of the electrical hook up. I ran the power directly from the battery. The scorpion grip has a 10 amp fuse from factory. Here is the link. Hope this helps. New joystick handle for the loader valve

Thanks. Your mod looks great. So you went directly to the battery rather than through the load center? I guess that works too.

I really considered the Scorpion handle, but I measuring it out and think it will sit too high up on the stick (I'm not that tall) and fear it would be uncomfortable. Since my stick is a threaded hollow tube, I would hesitate cutting it down or re-bending it. The closest I could come to what I want is the Scorpion P-series (https://www.controlgrips.com/p-series/), but they want $300.00 for one with a waterproof 3-position rocker switch. The P-Series is a lot more expensive than the S-Series because the P-Series is machined and the S-Series is molded. So I have decided to fab my own. I'll let you know how it works out.

Yes i went to the battery directly because i had other items i wanted to use for power. I also was in the same boat as you for the Joystick handle. So what i did was buy an extra metal bar for my 2032r for 40.00. Then i could cut, bend and do whatever i needed. So if i messed up i could return back to the way it was. Again that handle was one of the best mods i have done. With a grapple and my snowblower, my hand never leaves the Joystick and is very comfortable with all functions. Whatever you end up doing please post your outcome. Would like to see.
