The Goodman B1225020 Wiring Harness is the factory-terminated low-voltage wiring assembly for the ASH130181AC heat pump.

Specifications

Part number: B1225020
Component: Low-voltage control wiring harness
Fits: Goodman/Amana ASH130181AC heat pump
Connectors: OEM-keyed, pre-terminated plugs
Insulation: Heat- and moisture-rated jacketing
Wire colors: Factory-coded to the unit schematic

OEM vs. Generic

Genuine Goodman harnesses arrive with the exact connector bodies and pin-out your board expects — no crimping, no re-pinning, no guesswork. Building a harness from bulk wire risks reversed polarity on the reversing valve or a loose crimp that fails intermittently in the field. The OEM part restores the circuit exactly as designed.

Install Difficulty: Easy–Moderate (2/5)

Roughly a 15–20 minute job. Kill power at the disconnect, photograph the existing routing, unplug the old harness connector-by-connector, and clip the new one in following your wiring diagram. Basic hand tools only. If any connector is unlabeled, match it to the unit schematic before energizing.

Fits the ASH130181AC platform and backed by our exact-fit guarantee.
