Install Electronic Module
Refer to Figure 86
The electronic module reads the steering angle informa-
tion from either the CANbus or directly from the sensor
then converts the information to a PWM (percent duty
cycle) signal that is compatible with the Great Plains
3PYP steering system and outputs the signal to the
3PYP steering system.
Place the electronic module in a location in the tractor
cab where:
• it will not get damaged
• close enough to the 3PYP Steering System
Switch Box to connect the power wire.
Module Master Harness (Input)
Refer to Figure 87 and Figure 88
The input harness provides power to the module by con-
necting its 2 pin connector
to the 2 pin connector
from the Steering System Switch Box .
The gray colored connector on the harness attaches
to the gray colored plug on the translucent electronic
module
.
Select only one of the two other connectors to plug in:
(The selection is tractor specific.)
• the ISObus (connects to the tractor ISO diag-
nostics port) OR
• the Tractor Wheel Angle Sensor (3 pin connec-
tor that connects to one of the optional adaptor
harnesses listed below)
