Ground strap location / horn not working

[86Crockpot]

Ive read almost every post I can find about this issue and my horn isn’t working. It doesn’t work when I lock it or anything. Nothing else seems affected and fuse is good and I can hear the clicking under the hood when I push the horn. I’m thinking maybe it’s a bad ground? Some have referenced a ground near the overflow coolant tank but I just can’t find it. Could anybody point me in the right direction or anyone had luck tracking down this horn issue?

I downloaded this but still can't find the one that's by the overflow tank. Do you have a picture of this, or could you circle it on my pic of my engine compartment? I was reading about how this specific ground fails often.

I have been fooled by a fuse that looked good. Unless you can test the fuse with a multimeter, I would swap with a known good fuse even though it seems unnecessary and you hear a click. I don’t have access to my Jeep today but my first instinct is the horn ground would be in the area behind the driver’s headlight. Any other electrical work done just prior to the horn not working?

No prior electrical work done that I can tell. I just got this one a couple months ago.

Looking at the wiring diagrams it looks like the ground connection might be below the master cylinder.
