Goodman B1378700 16-Pin Wiring Harness

The Goodman B1378700 is a genuine OEM 16-pin wiring harness for the WGPH4530AMAB packaged unit and compatible Goodman/Amana systems. This harness carries the low-voltage and control connections between the unit control board and its components through a keyed 16-position connector. Melted, corroded, chewed, or intermittently failing connectors are a frequent cause of no-heat, no-cool, and erratic control board faults — a fresh harness restores reliable, clean connections.

Specifications

Part type: Wiring harness, 16-pin connector
OEM part number: B1378700
Brand: Goodman (genuine OEM)
Primary fit: WGPH4530AMAB
Connector: 16-position keyed plug
Function: Control / low-voltage interconnect

OEM vs. Generic

The OEM harness uses the correct pin assignments, wire gauge, color coding, and connector keying for your control board. A miswired generic or hand-spliced repair risks back-feeding circuits, blown fuses, or board damage. The factory harness plugs in exactly as the original and matches the wiring diagram on your unit.

Installation Difficulty

Moderate / Intermediate. Disconnect power at the disconnect, photograph the routing, unplug the old 16-pin connector and any inline terminals, route the new harness along the original path, and seat the connector fully until it clicks. Verify against the unit wiring diagram before restoring power. Basic hand tools and about 30 minutes.
