The Goodman 0259F00022 is a genuine OEM female wiring harness designed as a direct-fit replacement for the Goodman DMP150-52AB furnace. This pre-terminated connector assembly links furnace control components with the correct gauge wire, keyed connectors, and factory crimps — restoring clean, reliable connections when insulation is heat-damaged, terminals are corroded, or connectors are cracked or melted.
Using the OEM harness guarantees the exact connector housing, pin layout, and wire gauge your furnace's control board and components expect. Splicing in generic wire or mismatched connectors risks intermittent faults, voltage drop, and hard-to-diagnose electrical gremlins. The OEM plug-in harness makes the repair fast and foolproof.
Intermediate. With power fully disconnected, replacement is typically a straightforward unplug-and-reconnect job. Photograph existing connections before removal and verify each keyed connector seats fully. If any board-side pins are damaged, have a technician evaluate before energizing.
