The Goodman B1378701 5-Pin Wiring Harness is a genuine OEM sub-harness for the APH1560M41BA package heat pump. This 5-position harness connects a discrete component group — such as a motor, switch, or sensor branch — back to the main control circuit, delivering clean signal and power through a keyed factory plug. Damaged pins, heat-discolored housings, or brittle insulation cause dropouts and nuisance lockouts; a new OEM harness restores a solid connection.

  • OEM Part Number: B1378701
  • Part Type: 5-pin wiring harness / sub-harness
  • Connector: 5-position keyed plug (factory pinout)
  • Fits Model: APH1560M41BA (Goodman/Amana package heat pump)
  • Fit: Direct plug-in OEM replacement — no splicing

OEM vs. Generic: The B1378701 matches the exact connector keying and pin layout of the APH1560 wiring system. Aftermarket universal harnesses force splicing and can mis-key, risking reversed connections and component damage. For a reliable, code-clean repair, the factory harness is the right call.

Installation Difficulty: Easy (2/5). De-energize at the disconnect, unplug the old 5-pin harness at both ends, route the replacement identically, and click the new connectors into place. About 15–25 minutes with basic tools. Verify full seating before restoring power.
