When the implement's electrical system does not match the trailer connector, construct an adapter harness assembly. Use a 102-4090 Connector Plug to make the harness. A 102-4090 Connector Plug is available from any Caterpillar dealer.
See the implement's operator's manual for electrical requirements for the implement.
