Where is the Horn relay dodge charger 1973?

The horn relay on a 1973 Dodge Charger is typically located under the hood, near the horns themselves. It's often attached to the radiator support or inner fender well. The exact location might vary slightly depending on the specific model and trim level, so you'll need to look around that general area. A wiring diagram specific to your year and model would be helpful to pinpoint it precisely.
