The Goodman B1225020 Wiring Harness is a genuine OEM electrical assembly for the WGHP4660AAE packaged heat pump and compatible Goodman/Amana models. The harness delivers factory-routed connections between the control board, contactor, and load components using keyed connectors and color-coded leads, so it installs without splicing, crimping, or re-pinning terminals.

Specifications

OEM Part Number: B1225020
Brand: Goodman
Component Type: Wiring Harness
Designed Fit: WGHP4660AAE packaged heat pump
Connectors: Factory-keyed quick-disconnect terminals
Insulation: High-temperature rated for condensing-unit service

OEM vs. Generic

This genuine OEM harness is built to the precise lead lengths, wire gauge, and connector geometry of the original, dropping into the existing routing path. Universal harnesses typically require hand-matched terminals and cut-to-length splices, adding labor and introducing failure points. The OEM part guarantees a clean, correct, code-compliant connection.

Installation Difficulty

Easy (1/5). Disconnect power at the unit, photograph the existing routing, unplug the old harness one connector at a time, and seat the replacement along the same path. No special tools needed. Always confirm the unit is de-energized before servicing, and consult a licensed HVAC technician if you are uncomfortable working around line-voltage wiring.
