I have tried that method and come up with 4 threads,
this current one titled: Help--I'm loosing my mind
next one titled: New power beyond valve versus hydraulic selector valve
another titled: Help with triple selector valve
and lastly: JD SCV Extra Ports Question
That's all I'm getting in my searches and not a single one details mounting the valve behind the right side of the seat, discusses working out the switching of the three solenoids to function as desired and shows all the plumbing, the thread I am talking about was something close to 10 pages long and had many posts from the installer with various pictures and descriptions of the steps involved. The thread was started by the installer and I recall that one of the posts showed a bunch of hoses and fittings laid out with a comment about it being amazing how many parts and fittings the install was taking and that the items in the photo was not all of it.
I just am at a loss to explain why I have not been able to find the specific thread again, very frustrating.
