WARNING:
Only the Main and Rack Actuator Relays are required for the function of the Yanmar ECO engines. These relays are
supplied with the distributor standard specification engines in the loose parts box. The optional Sub-Relay connector (CR5)
is intended to activate 4 optional features such as engine stop switch, droop-switch, ECO lamp, and engine speed monitor.
All of these optional features are located in the accessory connector (J18) in the wire harness on pins 3,4,5, and 6. In the
event that these features need to be activated one additional relay P/N: 198461-52950 must be ordered from the Yanmar
merica Part Department.

resistance.
A relay mounting bracket has been provided with the kit. This bracket w ill allow the relays to be securely fastened to the

engine to reduce vibration and water damage.
Please see the next page for detailed installation instructions.
Be sure battery cables are connected correctly. Disconnecting either the positive or negative battery cable while the
equipment is operating will cause premature failure of electronic components. Also, never weld on equipment wit h the
ECU connected to the wire harness.

For applications that remotely mount the ECU within the wire harnesses reach please use the following ECU mounting
guidelines:
1-
Install the ECU in a location that is not subject to steam or high-pressure water for cleaning
2-
Install the ECU in a location that is well ventilated and not subject to direct sunlight.
3-
Install the ECU so that the connector faces downward. Failure to do so may trap water in the connector, resulting in
corrosion of connector pins.
4-
Ensure no water is trapped inside the connector when plugging the connector. Water inside the connector may
corrode connector pins, resulting in malfunctioning of the ECU.
