Goodman B1378701 5-Pin Wiring Harness

The Goodman B1378701 is a genuine OEM 5-pin wiring harness designed for the APH1543M41AB packaged heat pump and compatible Goodman/Amana equipment. This shorter sub-harness links a specific component — such as a motor, sensor, or relay — to the control circuit. Because HVAC control faults are frequently traced to a single damaged connector, replacing the exact 5-pin harness is often a faster, cheaper fix than swapping a whole board.

Specifications

Part Number: B1378701
Connector: 5-pin
Type: Component control wiring harness
Fits Model: APH1543M41AB heat pump
Brand: Goodman / Amana
Equipment: Packaged Heat Pump

OEM vs. Generic

Universal pigtails require cutting and crimping, introducing failure points and possible pin-order mistakes. The OEM B1378701 arrives with the factory 5-pin housing and pre-terminated leads, so it seats directly into the mating connector — reliable contact, no splices.

Installation Difficulty

Easy (2/5). Kill power, unplug the old harness at both ends, note the routing, and clip in the replacement. About 15–30 minutes with no special tools. The keyed connector only fits one way, preventing reversed connections.

Fits Goodman/Amana APH1543M41AB. Confirm the connector count and location before purchase.
