This wire kit provides the correct factory-specified wiring connections needed to maintain proper communication and power delivery between the control board and the ECM blower motor assembly.

About ECM Motor Wiring
ECM motors require both a main power harness and a separate low-voltage control harness for communicating speed and torque commands. The EW40030 wire kit is purpose-built to meet these requirements for First Company equipment, making it the preferred choice over generic aftermarket alternatives when performing warranty-quality repairs.
