| Have a 7330 tractor that is wired greenstar with the original plugs coming out of the corner post. Using the harness (PF90688) which goes from original plugs to gs3 , is there a way to hook into this with an atu? There is a 4 pin plug on the side of PF90688 that looks like it would be for this. However when I plug into it everything works perfectly, right up until it starts to steer itself. I can turn the auto track on, and when I hit the resume switch the "pie" goes to autotracking green and the atu does a slight flinch, then it cuts off and I get a message that says ' Steer controller communication error , no communication with vehicle steering controller. Check codes and contact 'customer no service' or I mean your dealer if ya know what I mean. My main question is that there doesn't seem to be a place for the smaller 2 pin plug on the atu harness to go which is probably the problem. I just don't know how to fix it. So to summarize of the 4 square plugs on atu harness ,2 have a terminator on them and the remaining 4 pin plug goes to display harness '90688' and the 2 pin plug goes nowhere. | |
