Near Intersection of I-35 & I-90 Southern Mn. | Your last point about needing a terminator at the back of the tractor when the implement with a module and terminators on it is disconnected makes good sense. Ag Leader used to provide a plug that acted as a dust plug and a terminator for the large AMP connector that is typically installed out the back of a tractor. This plug had a 120 Ohm resistor in it so when the implement cable was unplugged and the cap was installed the terminator issue was covered.
I have found that this cap is not always needed but still a good idea from a corrosion and dirt issue. I was surprised that the system continued to work fine with just the branch leading to the side of the tractor still operational and no terminator out the back. Maybe I just got lucky.

CANBus terminators... what are they anyway?
