Trying to convert a 8104 Terragator with an Air Max box that is controlled by a 661 Raven. Got harnessing from ag express and was assured it would work with a 661 controller. Anyways got the GRC hooked up and it will not run the belt. Has anyone tried to convert this to a GreenStar rate controller. I’m assuming the pins for the driver that controls the belts are not lining up but haven’t dug in that deep yet.
