The Goodman B1378701 5-Pin Wiring Harness is a genuine OEM connector assembly for the APH1524M41AA heat pump. This 5-position harness carries power and control signals between the board and a component sub-circuit — such as the fan motor or a sensor group — using a keyed plug for foolproof, correct-polarity connection. Frayed or heat-damaged harnesses trigger erratic operation and fault codes; a factory replacement restores clean, reliable signaling.

Part Number: B1378701
Type: 5-pin control wiring harness
Connector: 5-position keyed plug
Fits Model: APH1524M41AA (Heat Pump)
Wiring: Color-coded, factory-terminated leads

OEM vs. Generic

The genuine OEM part delivers the exact pinout, gauge, and lead length required — no guesswork. Generic alternatives demand hand-crimping and manual pin matching, raising the risk of miswiring. Choose OEM for a safe, warranty-friendly repair.

Installation Difficulty

Moderate (3/5) — Power off, label existing connections, and route the new harness along the original path. About 20–40 minutes. When in doubt, consult a licensed HVAC technician.
