Saw a post on X that mentioned there was a kit or components from Deere that allowed integrated hydraulic autosteer to be added on older Sound Gard cab tractors. Said that this allowed for more accuracy than the replacement steering wheel ATU type system.

1) Anybody done this conversion and know what all is required or replaced

2)  A part number or numbers for the components/kit/bundle needed

3) Any experience with accuracy over a ATU setup.

4) Anyone have a copy of this install manual that they could upload or scan

I copied this picture but can't quite make out the manual details other than seeing Autotrac hydraulic system for Sound Gard tractors on the cover.
