The OEM Goodman B1378701 5-Pin Wiring Harness is a genuine factory harness for the Goodman APH1536M41AC packaged heat pump. This shorter 5-position harness handles a dedicated component connection within the unit's low-voltage control circuit. Replacing a damaged harness — rather than splicing repairs into brittle or burnt wiring — restores a secure, keyed connection and eliminates intermittent faults caused by loose or corroded pins.

Specifications

Part type: Control wiring harness
Connector: 5-pin keyed plug
Function: Dedicated low-voltage component connection
Fits: Goodman APH1536M41AC packaged heat pump
OEM part number: B1378701

OEM vs. Generic

The OEM harness matches the factory wire gauge, colors, and 5-pin keyed connector exactly, so it drops in without cutting or crimping. Generic replacements invite mis-pinned or loose connections that are hard to diagnose later. For an inexpensive, plug-and-play repair, the genuine Goodman harness is the clear pick.

Install Difficulty

Easy. With power disconnected, unplug the old harness, route the new one along the factory path, and snap in the keyed connector. Basic hand tools and about 20 minutes are all that is needed — no refrigerant or soldering work involved.
