It includes real frustration points: no dealer schematic support, wrong initial hookup, and why hard pipe beat hoses in tight spaces. Best for owners mid-install on the same tractor.
Posted by an owner-operator documenting their own hands-on install with a right-to-repair mindset, not a dealer or professional installer.
You insert it in series between the power beyond of the loader control valve and the diverter valve, using the unmarked power beyond port, not a simple tee.
There was not enough room under the valve to run hoses, so hard piping was the only way to get the job done in that tight space.
The dealer would not cooperate, so the owner hooked it up wrong at first and later found a full service manual online for thirty dollars.
