The Goodman 2568416 HSI Wiring Harness is a genuine OEM replacement that carries ignition and control signals to the hot surface ignitor assembly on the GMP150-5 gas furnace. Over time the original harness can develop brittle insulation, corroded terminals, or intermittent connections that trigger ignition lockouts and no-heat calls. This factory-spec harness restores a clean, reliable connection so your furnace lights on the first try.

Type: Hot Surface Ignitor (HSI) wiring harness
Compatible Model: Goodman GMP150-5 gas furnace
Brand: Goodman

OEM vs. Generic

This is a genuine Goodman OEM harness, engineered to the exact gauge, length, and connector geometry of the original. Generic or spliced harnesses often use undersized wire and universal spade terminals that loosen with thermal cycling, leading to nuisance faults. The OEM harness plugs directly into existing connectors — no cutting, crimping, or guesswork.

Installation Difficulty

Easy (1 of 5). Disconnect furnace power, unplug the old harness at both ends, route the replacement along the same path, and reconnect. Typically a 10–15 minute job for a qualified technician. Always verify power is off at the disconnect before servicing.
