The Goodman B1378700 16-Pin Wiring Harness is a genuine OEM control harness for the Goodman AEPT030-00A-1 air handler.

OEM vs. Generic

The OEM harness is keyed and pre-pinned to drop straight into the AEPT control board — no pin-out reference or hand crimping required. Building an equivalent from generic connectors is error-prone and risks board damage from a single transposed wire. For control wiring, OEM is the safe choice.

Installation Difficulty

Beginner to Intermediate — With power off, the keyed plug connects in one orientation. Confirm the matching board and routing before ordering; no special tools required beyond standard safety practices.
