The Goodman B1378701 is a genuine OEM 5-pin wiring harness built for the APH1524M41BA packaged heat pump and compatible Goodman/Amana APH-series models. This smaller harness typically links a sensor or accessory circuit — such as a pressure switch, defrost sensor, or motor lead — to the control board. Using the factory harness guarantees the connector keying and wire colors line up exactly with the board terminals.

Specifications

Connector: 5-pin keyed molded plug
Application: Goodman/Amana APH1524M41BA packaged heat pump
Type: Low-voltage accessory / sensor interconnect harness
Fit: Direct OEM replacement — plug-and-play

OEM vs. Generic

The OEM B1378701 provides the precise keyed connector and pin order the control board requires. Generic replacements can force you to cut, splice, and re-pin — introducing points of failure and voiding many fit warranties. For a few dollars' difference, the OEM harness eliminates wiring errors and callbacks.

Installation

Difficulty: Easy (1/5). Kill power at the disconnect, release the old connectors, and snap the new harness into place along the original routing. A typical swap takes under 10 minutes. Verify power is off before opening the control panel.
