ECU Installation

ECU Connections Overview

Option 1: In-cab

Mounting in the cab of the tractor is the preferred option, as it best protects the ECU and harnessing from the elements. Mounting the ECU in-cab is best suited to tractors with paneling, compartments or normally covered cab walls with enough room to mount the ECU.

Being mounted in cab will provide access to the following for the T3H-C002 ECU breakout harness:

Power via convenience plug or power strip
Arm/Engage Switch
Tablet
4-way ISOBUS connection from Greenstar ISO harness
Diagnostic ports for tractor CAN access
Joystick
Valve output connections to JD legacy inputs or Case EHR inputs

Cabling will need to be run outside of the cab if:

Proportional solenoid or Danfoss PVE valve cabling must be run out to an external valve block

Option 2: Rear-panel

In situations where the cab doesn't have enough suitable space for mounting the ECU and neatening the harnessing, the ECU can be mounted at the back of the tractor

Option 3: Rear ISOBUS

Recommended in these situations

Mounting Information & ECU Dimensions

Dimensions Drawing

Magnets

Mounting with strong neodymium magnets can provide a quick and robust method of mounting the COMMAND ECU.

Neodymium magnets with a countersunk centre hole of 7mm diameter along with 7mm fasteners should be used.

Rivnuts

Mounting with Rivnuts is another effective way of securing the ECU to the inner or outer wall of the tractor.

Care should be taken to drill an appropriately sized hole of the Rivnut, then use the expansion tool and fasten the ECU securely.

Mounting orientation

The COMMAND ECU should be mounted with the electrical connectors facing downward. Doing so will reduce any possibility of ingress by moisture or dirt. Do not mount the ECU with the connectors facing upward or to the side as moisture or dirt may accumulate and cause corrosion and/or connection issues.

Connecting the ECU Breakout Harness

Once mounted securely in place, the T3H-C002 should be connected to the COMMAND ECU at the black and beige paired ECU plugs. Push each plug in until a click is heard or felt and the pull on the plug lightly to ensure that it has mated correctly.

To unplug the ECU connection, press down on the tab at the top of the connectors (facing toward you with the ECU mounted in the direction specified above. While holding the tabs, pull the plug downward to disconnect.
