Default 2004 Ford Ranger Horn not working

My horn doesn't work. It's not the fuse. when i press the button i can hear a clicking near the relay box on the passenger side. No diagrams list a horn relay. After a lot of hunting i found out that there are hidden relays on the back of the relay pannel. here's a link about that :

I was told it was probably a clock spring problem.

my questions:

1) If i can hear the relay clicking does that mean the clockspring is not the issue?

2) If I can hear the relay clicking does that mean the relay is working?

3) can anyone explain the wiring on the horn for this truck, i was considering by passing all this stuff and just running a wire to the a new toggle switch on my dashboard, but I'm not sure exactly how to do this. it is a 2 horn setup with two wires coming from it, neither of which are labeled for polarity. Any advice would be helpful.

Use a volt meter and probe the wires connected to the horn itself. Have someone inside the truck trying to honk it while you do this..

If it gets 12 volts and still doesn't honk then you've found your problem.
