Goodman B1378701 5-Pin Wiring Harness

The Goodman B1378701 is the genuine OEM 5-pin wiring harness for the APH1524M41AB heat pump. This pre-terminated sub-loom connects a discrete component circuit — such as the fan motor, sensor, or reversing-valve leg — to the control board through a keyed 5-position plug. Burnt terminals, brittle insulation, or a loose connector in the original harness cause intermittent faults, tripped components, and hard-to-trace no-run conditions. This factory replacement restores a secure, correctly pinned connection.

OEM Part Number: B1378701
Compatible Model: APH1524M41AB (Goodman/Amana Heat Pump)
Connector: 5-pin keyed harness
Terminals: Factory-crimped, correct gauge and pinout
Insulation: Heat- and abrasion-resistant jacketing

OEM vs. Generic

Even a small harness depends on exact pin count, wire color, gauge, and connector keying to seat and carry the correct signals. Generic replacements invite miswiring or a plug that won't lock. This genuine OEM harness matches Goodman's pinout for a plug-and-play fit.

Installation Difficulty: Moderate

Rated Moderate — no refrigerant work, but disconnect power first, label the original routing, and verify the connector clicks fully home. Basic low-voltage care is required.
