Goodman 0259F00018 12-Pin Wiring Harness

The 0259F00018 is the genuine OEM 12-pin main wiring harness for the Goodman/Amana AMH80904BNAB gas furnace. It carries low- and line-voltage connections between the integrated furnace control board and key components. Melted pins, corroded terminals, or rodent-chewed wires cause intermittent operation, blower faults, and hard-to-trace no-heat conditions — a fresh harness restores clean, reliable connections in minutes.

Specifications

Part number: 0259F00018 (OEM Goodman/Amana)
Type: 12-pin main control wiring harness
Connector: Keyed 12-position plug for control board
Application: AMH80904BNAB and compatible Goodman/Amana furnaces
Color-coded leads matched to factory wiring diagram

OEM vs. Generic

OEM harnesses use the exact keyed connector, wire gauge, and lead lengths specified for this chassis, so the plug seats fully and terminals hold tension. Generic or hand-spliced harnesses risk loose pins, incorrect gauge, and voided warranty claims. For a $24 part that touches every major component, OEM is the smart insurance.

Installation Difficulty: Easy

Rated 2 of 5. Fully keyed plug-in replacement — no splicing required on most units. Kill power at the disconnect, photograph the existing routing, unplug the old harness, and seat the new one until it clicks. Typically a 15–20 minute job.
