2 Great Plains Manufacturing, Inc. Front Page Part Lists Tractor Sensor Module Installation
401-768M Front Page Part Lists 06/16/2011
Descriptions of Module Components
Electronic Module
Refer to Figure 3
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 4 and Figure 5
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)
