The Goodman B1378700 16-Pin Wiring Harness is the genuine OEM main control harness for the APH1560M41AB packaged heat pump. This factory-terminated harness carries low-voltage and control signals between the unit's control board and its components through a keyed 16-position connector. Melted terminals, chafed insulation, or a cracked connector housing cause intermittent faults, no-heat/no-cool calls, and burnt pins. Replacing the harness with the exact OEM part restores clean, correctly-pinned connections without splice repairs.

Specifications

Part number: B1378700 (OEM)
Type: 16-pin main control wiring harness
Connector: Keyed 16-position plug
Fits model: APH1560M41AB packaged heat pump
Equipment: Goodman / Amana 5-ton (60,000 BTU) heat pump
Build: Factory wire gauge, colors, and crimped terminals

OEM vs. Generic

The B1378700 arrives pre-terminated with the correct pinout, wire colors, and lead lengths, so it plugs straight into the board and mating components. There is no true universal equivalent — building a 16-pin harness by hand risks pinout errors and unreliable crimps. The OEM harness is a plug-and-play fix.

Installation Difficulty

Moderate (3/5). Disconnect power, photograph the routing, unplug the old harness at both ends, route the replacement along the same path, and reconnect the keyed plugs. Around 30–45 minutes; a wiring diagram is helpful to confirm connector locations.
