Goodman 0259F00018 12-Pin Wiring Harness

The Goodman 0259F00018 is a genuine OEM 12-pin wiring harness for the AMH80904BXAA gas furnace and compatible Goodman/Amana models. This factory-terminated harness routes low-voltage and control signals between the integrated furnace control board and the furnace's components through a keyed 12-pin connector. When wiring is chafed, melted, or a connector is damaged, replacing the complete OEM harness is faster and more reliable than splicing individual leads.

The harness arrives pre-crimped with the correct gauge wire, pin count, and keyed plug so it seats into the control board exactly like the original.

Specifications

OEM Part Number: 0259F00018
Type: Wiring harness / connector assembly
Connector: 12-pin keyed plug
Fits: AMH80904BXAA and compatible Goodman & Amana furnaces
Construction: Factory-crimped, correct-gauge conductors

OEM vs. Generic

There is effectively no universal substitute for a molded 12-pin harness. The OEM 0259F00018 guarantees correct pinout, wire colors, and connector keying, avoiding miswiring and intermittent faults. Hand-built or generic harnesses risk pin mismatches and control errors, so OEM is the correct and safest replacement.

Installation Difficulty

Moderate (2/5). Unplug the old harness at the control board and its component ends, note the routing, and install the new harness the same way. Photograph connections before removal. Typical install time 15–25 minutes. Shut off all power to the furnace before servicing.
