The Goodman 0259F00018 12-Pin Wiring Harness is a genuine OEM connector assembly for the AMH80704BNAB gas furnace and compatible Goodman and Amana models. This harness links the integrated control board to the furnace's key components, and replacing a melted, corroded, or damaged harness restores clean electrical connections and eliminates intermittent faults caused by loose or burnt terminals.

Specifications

Type: 12-Pin Wiring Harness / Connector
Pins: 12
Part Number: 0259F00018
Fits: AMH80704BNAB and compatible Goodman/Amana furnaces
Equipment: Gas Furnace
Includes: Molded plug harness with pre-terminated leads

OEM vs. Generic

The authentic OEM Goodman harness uses the exact keyed 12-pin plug, wire gauge, and color coding your control board expects, so it seats correctly the first time. Generic or hand-spliced repairs risk mismatched terminals, poor contact, and resistance heating that can damage the board. This plug-and-play harness removes the guesswork and protects your furnace's electronics.

Installation Difficulty: Easy

Typically a 15-minute swap. Disconnect power at the furnace, unplug the old 12-pin connector from the control board, note the routing, and plug in the new harness — the keyed connector only fits one way. Secure any wire clips and confirm the terminals seat fully. Restore power and run a heat cycle to verify normal operation. No cutting or crimping is required with this direct-fit OEM part.

Ensure reliable control-board connections in your AMH80704BNAB furnace with this genuine OEM 12-pin wiring harness.
