1.5 Complete in-field tuning There are a few final adjustments to be made in the field. 1. Bump TrueSight to center the snout on the row. o Twist the knob in the desired direction when in the run screen. 2. If the display shows that you are not centered (see red circle above) - Calibrate the bump centered position.
2 Installation 2.1 Harness installation 2.1.1 Wiring overview The main harness shown is the backbone of the TrueSight system, connecting each of the components to the controllers. The harness is divided into three main legs designated by the circles above. 1.

3. The “Steering Device” leg connects to the valve or motor which will steer the combine. o For Trimble valves this will exit the cab with leg 2 o For Outback, EZ-Steer, or other wheel-mount motors, this leg will remain in the cab A: In-cab components (Leg 1) B: Crop sensor (Leg 2) C: Wheel Angle sensor (Leg 2)
When given an instruction for a connector with a number beginning with “Y” (e.g. Y345) this refers to a Headsight connector. If the instructions say to “connect Y123 and Y234 inline” this means you will disconnect the OEM connector indicated, connecting Headsight connectors Y123 and Y234 to the mating connectors indicated.
2.1.4 Power supply 1. Connect Y252 to the auxiliary power connector o Located on the right rear of the o You may need to slide the seat all the way forward and remove the two screws holding the Acc. power box to find the power plug shown.

linkage must always clear obstructions; the block is preferably mounted as shown with the sensor on top of the block. 1. Choose an installation location where the sensor and linkage will be out of the path of travel of the tie rod, and the components will be out of the flow of chaff as much as possible.
2.3 Steering device wiring 2.3.1 Trimble AutoPilot 2.3.1.1 Trimble AutoPilot with Nav2 1. Connect Y742 to male override connector and Y743 to female connector on platform harness in cab. 2. Connect Y740 to male valve connector andY741 to female connector on platform harness in cab.
2.3.1.2 Trimble AutoPilot without Nav2 1. Connect Y717A to Y717 on Truesight main harness. 2. Connect Y718A to Y718 on Truesight main harness. 3. Connect Y742 to male override connector and Y744 to female connector on platform harness in cab. 4.

2.4 Crop sensor installation 2.4.1 Sensor assembly 1. Choose your headers row spacing range. o For row spacings 30” and above use the arm 30”+ position shown by the blue arm. 28”- o For row spacings less than 30” use the arm position shown by the yellow arm.
2.4.2 Width adjustment 1. Loosen the jamb nut indicated. 2. Turn arm adjustment screen using a hex (allen) wrench. o Adjust arm width to row spacing plus 2 inches (e.g. adjust to 32” for 30” row spacing) 3. Tighten jamb nut 2.4.3 Safety reminder Before working under the header always: 1.
2.4.5 Sensor mounting 2.4.5.1 John Deere 90 series heads 1. Attach the sensor to the mounting bracket as shown. 2. Attach bracket to snout. o Use provided button head bolt in rear hole. o Re-use previously existing hardware in front hole. 3.
2.4.5.2 Other heads Specific sensor mounting instructions for other header and snouts are included with the sensor mounting bracket kit for that header. 2.4.6 Wiring instructions Properly routing the wiring is the most critical part of the installation process.
3 Operation 3.1 Controls description There are only two controls on TrueSight: 1. “The Button” o Tapping the button Engages/Disengages TrueSight o Holding the button for more than 1 second Enables/Disables the Auto-Engage feature 2. “The Knob” o The knob functions differently in the menu and the run screen ...

4 Settings 4.1 Range (Default = 40) The range setting controls the aggressiveness of the Truesight system. Increasing the range increases the angle to which the wheels turn. To adjust the range – go to: Setup>>Range in the menu. Properly adjusting the range is the most important step for optimum steering response.
To change this setting – go to: Setup>>Aux Engage in the menu. If you choose to use the Headsight provided footswitch – choose “Default”. If you do not wish to use any auxiliary switch – choose “Off”. If you wish to use a switch other than the one provided, contact Headsight for assistance.
Decrease the deadband if: The system wanders in the row without even trying to turn the wheels. Increase the deadband if: The system is steering excessively often even on relatively straight rows. 4.9 Auto-engage delay (Default = 2.5 sec) The Auto-Engage Delay adjusts the time delay between when the operator lowers the header and Truesight engages when using the Auto-Engage feature.
4.14 Left Deadzone (Default = Calibrated Value, 0 if not calibrated) The Left Deadzone setting allows manual manipulation of the minimum output of the Truesight system when turning left. This value is expressed in % of the maximum speed. To change this setting – go to: Setup>>ADV Settings>>Left Deadzone in the menu.
5 Calibration 5.1 Bump centering calibration The bump centering calibration only serves to simplify the display on the remote controller; it does not affect the operation of the TrueSight system. To perform the bump centering calibration – go to: Calibration>>Bump Center in the menu.
5.3 Auto-engage sensor calibration The Auto-Engage sensor calibration learns a feederhouse position at which to engage TrueSight. To perform the Auto-Engage calibration – go to: Calibration>>Auto-Engage in the menu. When the header passes below the chosen height, TrueSight will delay a short time (see Auto-Engage Delay in the Settings section) and then begin steering.
