3rd function/remote ?

The John Deere factory kit terminates them just above the cross member pointing down but slightly angled towards the center.

Here is how I attached mine. There are 2 bolts holding the cover plate onto the cross bar, so I got 2 longer ones. I used bulkhead fittings to mount the couplers to the plate. 1/4" steel, IIRC. Very similar to how Kubota did their factory 3rd function on these models.
