Goodmark GMK401226372 OE Replacement Horn Relay

The Goodmark GMK401226372 is a new OE-replacement horn relay designed to restore proper horn function on classic GM muscle cars and full-size vehicles from the 1972–1973 model years. This direct-fit replacement matches the original factory relay in form, fit, and function, making it a straightforward swap for worn or failed original equipment.

The horn relay serves as the electrical switching component between the horn button and the horn itself, allowing the low-current signal from the steering wheel to trigger the higher-current circuit that actually sounds the horn. A faulty relay is one of the most common causes of a non-functioning horn on these classic vehicles.

Key Features:

• New OE-style replacement horn relay — not a rebuilt or remanufactured unit
• Designed to meet original manufacturer specifications for proper fit and function
• Direct-fit replacement for a straightforward, no-modification installation
• Part of the Goodmark Electrical Components product line
• Manufacturer part number: GMK401226372
• Backed by a Goodmark 120-day warranty against defects in materials and manufacturing
