Tractor Sensor Module Installation
Descriptions of Module Components
Electronic Module
Refer to Figure 3
The electronic module reads the steering angle information 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 connecting its 2 pin connector 1 to the 2 pin connector 5
from the Steering System Switch Box 7 .

Optional Adaptor Harness
Refer to Figure 10, Figure 11 and Figure 12
If obtaining the tractor wheel angle signal from the CANbus on the tractor is not possible, the signal can be
obtained directly off the electronic sensor. To do this, an
adaptor harness is required. The appropriate harness is
used to tap into and monitor the existing steering angle
sensor signal from the tractor. There are currently three
variations of this harness:

series of lights are visible.

The light labeled STATUS 2 indicates the heartbeat of
the program. This light is a flashing red light when the
program is operating properly.
SETTING 1 This is a constant green light when the module detects itself being connected to a John Deere tractor
through the steering angle sensor.
SETTING 2 This is a constant green light when the module detects itself being connected to a Case/New Holland
tractor through the Steering Angle Sensor.
SETTING 3 This is a constant green light when the module detects itself being connected to a John Deere tractor
via the ISObus diagnostics port.
SETTING 4 through 8 For future use.
CAN STATUS 3 This is a constant green light when the
module detects the CAN signal.
Null4:
SIGNAL OUT 1 through 6 These lights are active when
the module is directly connected to the tractor Steering
Angle Sensor (Setting 1 and 2). The number of lights lit is
based on the angle of the wheels. The intent of the
series of lights is, as the steering wheel is turned from
full left to full right the number of Signal Out lights illuminated will change. This change in the number of lights
illuminated lets the operator know the signal from the
tractor is changing.
Since the value of the signal is based solely on the tractor, at any given position of the steering wheel the number of lights illuminated may not be the same.
EXAMPLE: When the system is connected to Tractor X a
hard left turn may have only SIGNAL OUT 1 illuminated.
As the steering wheel is turned toward a hard right, a
progressive number of SIGNAL OUT lights may illuminate. Whereas if the system is connected to Tractor Y, a
hard left turn may have several SIGNAL OUT lights illuminated instead of just one. And as the steering wheel is
401-768M

turned toward a hard right a progressive number of SIGNAL OUT lights go out instead of light up.
When installing the module no settings need to be
changed and no calibration of the module is required.
When the module is installed and the steering system is
powered on the appropriate lights illuminate. At this point
follow the instructions for steering system calibration
located in the Operator Manual (3PYP manual number
401-312M or 3PYPA manual number 401-647M).
