Hello all. Very pleased to finally report some kind of success with my v4 std board, single antenna, steer motor kit.
Started this project over 2 years ago now and been thinking about building an agopengps kit for much longer, but life has always got in the way.
Anyway initial testing is complete, now waiting for it to dry up and the slurry season start to fine tune the steer system. Haven’t seen much documentation for CNH machines so here’s my take.
The motor bracket clamps around the steering column like so, with adjustable height to find the right position. Also built in a quick release mechanism for road work/ease around the yard, also helpful when panic hits and the motor does unusual things during initial setup!

PCB enclosure is fastened to the fire extinguisher bracket down the side of the seat. Convenient for wires running under the mat to the steering column, and through the floor to the battery compartment and down the chassis to the WAS
ON switch located in the pillar behind right shoulder.
I also modelled and 3d printed a bracket for the tablet holder that fits into the motor rail similarly to the existing ones, just decided to make one rather than buy! Came out really well
WAS bracket made out of metal, uses the same bolt holes as the bracket for the pivoting fenders, just bolts in underneath
Antenna bracket bolted to the roof through the rear central bolt hole
All bracketry is first stage prototyping just to get the system running effectively! Further finesse/finery is to come once it has started paying itself off!

Thank for sharing your journey.
I installed the same setup on my tsa135 about 3 years ago. It works very well. If i was to do it again id definitely fit the keya motor, getting that phidgets motor to fit tidy was more work than i anticipated at the time.
Did you try using the tractors own WAS on the right hand wheel or was it knackered
(pretty common to fail)
Your tablet mount bracket looks smart 
This forum has been so helpful to me, looking forward to giving something back!
No never looked into it’s own WAS, and I have no idea how autosteer ready this tractor already is so I just went for the complete bolt in system to start off with.
I agree, I think the steer motor and 3d printed gears will let the system down when performing in the field, just because the plastic around the steering wheel is so bulky, it’s hard to get a good fit. Once I know it’s all up and running well I want to put the hydraulic valve in
