The Goodman 2568416 HSI Wiring Harness is a genuine OEM hot surface igniter harness for the GMP125-5 gas furnace and compatible models. It delivers line voltage from the control board to the igniter through high-temperature insulated leads and factory connectors, so ignition timing and current stay within spec. Melted insulation, brittle wires, or corroded terminals near the burner box are common failure points that cause no-ignition or intermittent lockout faults — this pre-terminated harness restores a reliable connection.

Specifications

Part number: 2568416
Type: Hot surface igniter (HSI) wiring harness
Insulation: High-temperature rated leads
Connectors: OEM plug terminals, pre-crimped
Fits: GMP125-5 and compatible Goodman furnaces

OEM vs. Generic

This OEM harness uses the correct gauge, high-temp insulation, and factory connector housings so it seats exactly like the original. Generic pigtails often require splicing and may not tolerate the heat near the burners. For the igniter circuit, OEM is the safe choice.

Install Difficulty

Moderate (2/5). Disconnect power, photograph the routing, unplug the harness at the board and igniter, then route and reconnect the new harness away from hot surfaces. No splicing required with the OEM part.
