The Goodman 0259F00007P is a genuine OEM 12-pin wiring harness designed for the GMTH070-4 gas furnace and compatible Goodman/Amana equipment. This factory connector assembly links the integrated furnace control board to key components, delivering clean, keyed connections that prevent miswiring and intermittent faults. Damaged, melted, or corroded harness connectors can cause erratic operation, no-heat calls, or blower and ignition issues, making a direct OEM replacement the fastest path to a reliable repair.

Specifications

Configuration: 12-pin harness / connector assembly
Brand: Goodman OEM
Application: Furnace control wiring
Fits: GMTH070-4 and compatible Goodman models
Part number: 0259F00007P

OEM vs. Generic

The OEM 0259F00007P uses the correct pin count, keying, gauge, and terminal crimps to match the furnace control board exactly, ensuring a plug-and-play fit with no splicing. Generic or universal harnesses may require cutting and crimping and risk pin-position errors. For a guaranteed factory fit and dependable connection, choose the OEM harness.

Installation Difficulty

Easy to Moderate (~15–25 minutes). Power off the furnace at the breaker before servicing. Unplug the old harness at each keyed connector, route the new harness along the same path, and seat each connector until it clicks. Because connectors are keyed, mismatched insertions are unlikely, but verify each mate before restoring power. Consult a licensed HVAC technician if you are unsure.
