This wiring harness connects the electrical system of the baler, routing power and signals between the control unit and the actuators on the machine. It replaces the original assembly and maintains the correct pin configuration and wire gauge for the circuit loads. A damaged harness causes intermittent or complete loss of function in the tied components, such as the tying mechanism or density control. The harness is built to the original routing lengths and connector types, which avoids splicing or adapter use during installation.
