Near Intersection of I-35 & I-90 Southern Mn. | Not much help but I believe the Integra used a four pin connector for CAN communication. An InCommand uses a 6 pin connector to connect to an ISO device for communication and supplemental power/ground. This tends to be reinforced by the colors used.
With a four pin connector there is a red for power, black for ground and a Green & Yellow pair for CAN High and CAN Low.
With a 6 wire situation the above four wires are used but supplemented by a red with stripe and black with stripe. It is my guess that this pair is another power/ground source. There may be situations where a 4 pin connector on the display cable needs to be mated with a 6 pin connector on the 3rd party device or where a 6 pin connector on the display cable needs to be mated with a 4 pin connector on the the 3rd party device.
There may even be other situations where having the extra supplemental power/ground could back feed from one device to the other and could cause damage.
Possibly this is not the correct adapter for your situation. This adapter indicates InCommand. From your description I don't believe you are using an InCommand with your setup. .
The reason I became aware of both a 4 pin and a 6 pin connector ISO connection was when I installed a Truesight II feeler steering system on my combine. The Truesight wiring harness had both a four pin connector and a six pin connector available for the ISO communication between the display and the Truesight system. The instructions indicated using which ever one was present on the Ag Leader display cable. The other unused connector on the Truesight cable would not be used. In my situation, I plugged in the six pin connectors and taped the unused 4 pin connector back. This worked fine and the Truesight setup appeared on the InCommand Screen.
I don't know why the extra wires were added but possibly it is necessary to provide supplemental power/ground to some 3rd party device. Thus the original four wires are used and supplemented with another pair of power/ground wires.
It would be helpful to see the entire adapter wiring drawing. From what I can see, one of the six pin connectors only uses 4 of the 6 pins. This part puzzles me since if only 4 wires are being used, I would think that the connector would just be the four pin style. Possibly this is for a situation where the "other" device (NORAC) uses a 6 pin connector but allowing power/ground coming from it back to the Ag Leader could cause a problem.
