OEM Goodman 0259F00018 12-Pin Wiring Harness

The Goodman 0259F00018 is a genuine OEM 12-pin wiring harness for the AMH81405DNAB gas furnace and compatible Goodman/Amana models. This harness carries low- and line-voltage signals between the integrated furnace control board and connected components. Cracked insulation, melted connectors, corroded pins, or rodent damage can cause intermittent operation, error codes, or a furnace that won't respond to a call for heat. Replacing the harness with the exact OEM part restores clean, reliable connections.

  • OEM Part Number: 0259F00018
  • Compatible Model: AMH81405DNAB (Amana/Goodman gas furnace)
  • Connector: 12-pin plug
  • Function: Control board interconnect wiring
  • Equipment Type: Furnace

OEM vs. Generic

Wiring harnesses are model-specific: the OEM 0259F00018 has the exact connector housing, pin count, wire gauge, and color coding to plug in without splicing or re-pinning. Universal or spliced-together substitutes invite miswiring, voltage drop, and future connection failures on a safety circuit. For anything carrying furnace control signals, matching OEM is strongly preferred.

Installation Difficulty

Easy (2/5). Disconnect power, unplug the old harness at each keyed connector, route the new harness along the same path, and re-seat the plugs. Photograph connections first. Most installs take 20–30 minutes.
