With ignition key on, check each Section Drive Output pin on the existing tractor harness for
voltage (refer manufacturer of existing tractor harness for pin detail). Locate where voltage
is supplied to determine if it can be removed without limiting existing functionality.
If it is not possible to remove this voltage then you must install a Section Drive Output
Protection Adaptor. (A2812 for 37-pin on Connector 1 and A2813 for 16-pin on Connector 3)
If no voltage is found disconnect the vehicle's battery and continue with installation.
