The Goodman B1378701 is a genuine OEM 5-pin wiring harness built for the Goodman AEPF303616BA air handler and compatible Goodman/Amana fan-coil models. This shorter connector assembly carries the low-voltage and accessory connections between the control board and downstream components, restoring factory wiring after a damaged plug, corroded pin, or chewed lead.

Specifications

Part type: Multi-pin wiring harness / connector assembly
Pin count: 5-pin connector
Equipment: Air Handler (fan-coil)
Fits model: AEPF303616BA
Brand: Goodman (also fits select Amana units)
Build: OEM-spec keyed plug, color-coded leads, correct wire gauge

OEM vs. Generic

The genuine OEM B1378701 matches the original connector keying and lead lengths exactly, so it clicks into place without splicing. Universal generic harnesses typically force you to cut and crimp, which introduces failure points and voids the clean factory look. For a small 5-pin connection, the OEM part is inexpensive insurance against repeat callbacks.

Installation Difficulty

Easy — true plug-and-play. Kill power at the breaker, unplug the old harness at both connectors, route the B1378701 along the original path, and seat both plugs. Most installs take under 15 minutes.
