Default Where's the Horn Relay located on a 66 Bonneville?

Wondering where the horn relay is located. I know the horns are upfront between the grille and rad. But where's the horn relay located? Firewall? Where about? I have the manuals and cany seem to even spot a picture of the firewall either..
Would be greatly appreciated.

On my Catalina the horn relay is mounted near the fender side / front corner of the battery tray on the edge of the core support.

If there is no clicking when pressing on the horn. Does that mean the relay is bad?

Do you have power going to it? You may have lost the ground at the rag joint.

Correct me if I'm wrong (it's a long time since I looked at this area), but my understanding is the horns have constant power to them and the circuit is made by when pressing the horn bar, you create the ground.

In exactly the same way the wipers work and the interior light works. You create the circuit by grounding the item.

In the case of the horn relay, it is connected directly to the battery and the wire from the horn bar trips the relay creating the noise. So if you simply pull off the ground wire from the relay, use a loose piece of wire and touch it between the relay ground and the ground side of the battery, if you get noise, the relay is working and you then need to trace back to the horn bar to establish the fault.
