The Goodman B1378700 is a genuine OEM 16-pin wiring harness engineered for the Goodman AEPF303616BA air handler and compatible Goodman/Amana fan-coil units.

Specifications

Part type: Multi-pin wiring harness / connector assembly
Pin count: 16-pin connector
Equipment: Air Handler (fan-coil)
Fits model: AEPF303616BA
Brand: Goodman (also fits select Amana units)

OEM vs. Generic

The genuine OEM B1378700 uses the exact connector keying, wire gauge, and lead lengths as the original, so it seats correctly the first time with no splicing or re-pinning. Generic universal harnesses often require cutting, crimping, and guesswork that can cause intermittent faults. For a 16-pin control connection, OEM fit is the safest path to a clean repair.

Installation Difficulty

Easy — plug-and-play replacement. Disconnect power, unplug the old harness at both ends, and route the new B1378700 along the same path. Typical install is 10–20 minutes for a technician or a confident DIYer. Always disconnect power at the breaker before servicing.
