Genuine Goodman 12-Pin Wiring Harness 0259F00018

Replace damaged, melted, or rodent-chewed wiring on your Goodman/Amana AMH81155CXAA furnace with this OEM 12-pin harness. It carries low-voltage and control signals between the integrated furnace control board and key components, and its keyed 12-pin connector ensures every wire lands in the correct position. Using the factory harness eliminates the miswiring risk that comes with cutting and splicing individual conductors.

Specifications

OEM Part Number: 0259F00018
Connector: Keyed 12-pin plug
Fits: Goodman & Amana AMH81155CXAA and compatible furnaces
Color-coded conductors matched to factory wiring diagram
Molded strain-relief terminals for secure seating
Rated for furnace-cabinet operating temperatures

OEM vs. Generic

This OEM harness arrives pre-terminated with the exact connector and pinout your control board expects — plug it in and go. Generic replacements require crimping your own terminals and matching the wiring diagram by hand, introducing shorts, opens, and nuisance faults. For a component that ties the whole control system together, the factory harness is the safe choice.

Installation Difficulty

Easy–Moderate (2/5). Disconnect power, unplug the old harness at both ends, route the new harness along the original path, and seat both connectors until they click. Photograph the routing before removal. Typically 15–25 minutes.
