Near Intersection of I-35 & I-90 Southern Mn. | This is not a direct response to the OP's question but does concern some combinations of Ag Leader display cables and steering.
I had a situation where I wished to use Ag Leader's Steady Steer with a vehicle that already had the older legacy display cable from an earlier Ag Leader display. By using an adapter cable I could get my InCommand connected to the old display cable that was already nicely tucked in the rig. I preferred not to purchase a new display cable if possible.
Steady Steer could be connected to the rear of the InCommand 1200 with its separate ethernet cable with the 4 pin M12 connector.
The problem was that my old display cable did not have the High Current power source nor the Guidance Activation source branches. These connectors would be available on the newer cable.
The purpose of the High Current connection is to provide a convenient high current power source to Steady Steer to do the "work" portion of steering. The purpose of the Guidance activation connection is to provide a convenient connection that goes ON/OFF with the InCommand to awaken Steady Steer.
Rather than purchasing a new display cable with those branches, I just made a stub cable with the High Current style connector that connects to a good 12V source in the vehicle. I also made another stub cable with the Guidance Activation style connector and connected it to a key switched source in the vehicle.
I did have another situation where I did switch to the newer style display cable. My Deere combine was using a display cable from my first Ag Leader Insight and an adapter cable to an InCommand 1200. This worked fine until I added Steady Steer to the combine by making the stub connectors as described above. This was fine also until I decided to add the Headsight Truesight 2 feeler steering system for corn.
The Truesight feeler system can utilize the Steady Steer motor as well as many others. It can also interface with various brands of hydraulic steering on combines.
The Truesight 2 system can use a separate display of its own or can use the VT portion of my InCommand 1200. I chose to go with the VT approach. However, this required an ISO connection which was not present in my ancient display cable. The simplest approach seemed to be to remove the old Insight display cable and replace it with one that had all the necessary branches on it. The new cable had the various branches that I needed.
Some might be curious as to how both steering systems are present and work. The Steady Steer motor is used in both situations.
For soybeans, I use the Steady Steer system as it would normally be installed. The Steady Steer SCM is connected to the Steady Steer motor. A momentary engage/disengage switch is connected to the Steady Steer controller. I create either a new AB line or reload an AB line from planting and Steady Steer steers the combine based on the line.
When I switch to corn, I unplug the cable leading from the Steady Steer system controller to the Steady Steer motor and plug the connector into the Truesight 2 controller. I also move the momentary engage/disengage switch from the Steady Steer System to the Truesight 2 system. These are the only two connections I need to change.
In corn, the steering is performed based on a set of feelers on the corn head. Typically I manually steer onto the correct set or rows as usual and the push the engage button. The combine is then steered based on the feelers. When I approach the far end, I disengage the system with the button, return to manual steering and make the turn around as usual. A VT screen on the InCommand is used for interaction with the Truesight system which is generally just for initial setup.
Both systems work very well although there is quite a maze of wiring in the cab.
