Horn Relay Location 74 Caprice

My horn isn't working, I trace the wire to the junction box behind the driver's side headlights. Should the horn relay be attached there? I can't find any diagrams for this location

You can follow the green wire from the horn back to the relay. From memory it is attached to the radiator core support to the battery side but my memory isn't that reliable any more. It might just as easily be on the fire wall near the AC air box as the relay was the pick up point for the main current feeding the car's interior cabin.

It's actually under the dash behind the ac/heat controls. Replaced the relay and still nothing. Pulled a horn out and tested on my Nova, the horns are bad.
