**NOTE:** The connection may be accessed from beneath the tractor, between the front of the rear-right wheel arch and the valve-block bracket. Removing the rear-right wheel and access panel provides additional access where required; follow the tractor manufacturer’s service instructions.
1\. Complete the machine preparation steps in **Section 5.1** and isolate the tractor electrical supply. [](https://docs.t3rra.com/uploads/images/gallery/2026-09/Uzeimage.png)2. Locate the valve/chassis harness connection behind the panel under the rear-right wheel arch, shown as **A** in the location image. **(A)** - Valve/chassis harness connection [](https://docs.t3rra.com/uploads/images/gallery/2026-09/7Avimage.png) 3\. Release the connector latch and disconnect the **valve harness receptacle (A — X1587\_P)** from the **tractor chassis harness plug (B — X1586\_S)**. **(A)** - Valve/Chassis Harness connection **(B)** - Front of the Rear Right Wheel Arch **(C)** - Valve Bracket, Inside Rear Right Wheel [](https://docs.t3rra.com/uploads/images/gallery/2026-09/XD1image.png) 4\. Connect the **4-way “VALVES” plug (C)** on the **S/111** harness to the **valve harness receptacle (A)**. **(A)** - Valve harness receptacle (X1587\_P) **(B)** - Chassis harness plug (X1586\_S) **(C)** - ‘VALVES’ Plug S/111 Adaptor Harness **(D)** - ‘TRACTOR’ Receptacle S/111 Adaptor Harness 5\. Connect the **4-way “TRACTOR” receptacle (D)** on the **S/111** harness to the **tractor chassis harness plug (B)**. 6\. Connect the **5-way plug** on the **S/111** harness to the **tractor-side receptacle** on **T3H-V005**. 7\. Connect the **5-way receptacle** on the **S/111** harness to the **valve-side plug** on **T3H-V005**. 8\. Route **T3H-V005** to the **COMMAND** ECU and connect it to the **CAN Interface** connector on the **T3H-C002** ECU breakout harness. 9\. Ensure all connectors are fully seated and latched. Secure the harness clear of the tire, moving parts, hot surfaces and sharp edges, leaving sufficient slack to avoid strain on the connectors. 10\. Refit any components removed for access. Keep **COMMAND** disarmed and restore the electrical supply.**IMPORTANT:** The 4-way valve-harness connection and the 4-way connection at the rear ISOBUS socket serve different purposes. Connect **S/111** to the valve/chassis harness connection identified above.
Where an ISOBUS connection is required for the installation, follow **Section 5.4** using the appropriate **COMMAND** cab or exterior breakout harness.
## Tractor Valve Configuration 1. Ensure the required tractor SCVs are enabled and unlocked using the tractor’s controls. 2. In **Level COMMAND**, select **Fendt SCR/S4/MT** as the valve interface. 3. Assign the required SCVs to the controlled functions, such as height and cross-slope. These assignments must match the implement’s hydraulic hose connections. 4. Prepare the selected SCVs for external control as described below, then verify that each function operates the intended valve in the correct direction. 5. Complete valve configuration and calibration before automatic operation. For detailed configuration and calibration instructions, refer to the **Level COMMAND Manual**. ## Operation Notes To prepare the selected SCVs for automatic control: 1. Ensure the required tractor SCVs are enabled and unlocked. 2. Move the **COMMAND Arm/Engage switch** to the middle **ON** position to arm COMMAND. 3. Move each selected SCV’s tractor control lever into the **float position** to enable external control of that valve. 4. Press the momentary side of the **COMMAND Arm/Engage switch** to engage automatic control once the system is ready.**NOTE:** For SCVs configured for **COMMAND** control, the lever’s **float position** enables external hydraulic control. It does **not** place the valve into hydraulic float.
**IMPORTANT:** To disengage **COMMAND** automatic control, press the momentary side of the **COMMAND Arm/Engage switch**. Move the switch to **OFF** to disarm **COMMAND** and disable its hydraulic control commands.
Before handing over the installation, verify manual valve operation and demonstrate how to enable, disengage and resume automatic control.
