Bard part number 3001-049 is an OEM terminal designation wire used in Bard wall mounted HVAC equipment to identify and organize wiring at terminals and connection points, helping technicians confirm correct wire landing during troubleshooting, board replacement, and control box service. In packaged wall mount units where multiple harnesses and low voltage circuits share the same compartment, a proper factory designation wire reduces miswiring risk and speeds up diagnostics by keeping the electrical layout consistent with Bard diagrams. If you are replacing a damaged or missing marker lead, use 3001-049 to maintain original wire identification and ensure your unit matches the intended service documentation and wiring practices.
