Hydraulic coupler valve

[typ4]

So im looking for a hyd coupler valve to replace on our fleet.
We have older JD equipment and the dealer is no help. They want to sell us a complete install kit.
The ones we have are mounted on the stick above the bucket cyl and use oil from that to run the coupler when the switch is activated. I dont like that arrangement.
Any help is appreciated.
Here is what we have

That looks more of a manifold with a logic valve vs a solenoid valve. Have you traced your lines back to source. I think you may have an AB solenoid valve down near the foot of the boom or near the MCV. good luck.

The solenoid is missing.
Turns out the maker is right here in portland so a trip is in order.
Hydro Power Systems.
I finally got to someone at deere that has been there a while that knew.
