The Goodman B1378701 5-Pin Wiring Harness is a genuine OEM electrical assembly engineered for Goodman WGPH4530AMAB packaged air conditioning systems. This pre-terminated harness connects the unit's low-voltage control circuit to the board and blower components, ensuring correct polarity and reliable signal transfer between major subsystems.

Built to factory tolerances with color-coded leads and locking 5-pin connectors, this harness eliminates the guesswork and miswiring risk of generic spliced alternatives. The molded plug seats securely to prevent vibration-induced disconnects common in rooftop and ground-mount package equipment.

  • Connector: 5-pin keyed plug
  • Fit: Goodman WGPH4530AMAB and compatible package units
  • Leads: Color-coded, OEM gauge wire
  • Application: Low-voltage control circuit
  • Part Number: B1378701

OEM vs. Generic: Our genuine OEM harness arrives with the exact connector pinout and lead lengths your unit expects. Generic universal harnesses require cutting, crimping, and matching pins by hand — increasing the odds of a control fault or no-start condition. The OEM part installs as a plug-and-play swap.

Install Difficulty: Easy (1/5). With power disconnected, unplug the failed harness and reconnect the new one at both ends. No special tools required; typical replacement takes under 15 minutes.
