Horn problems

I made a short video to ask about a horn problem. There are three horns on this truck but only oe has ever worked directly from the relay. The other two will work from a direct feed from the battery but not from the relay. Any idea why that would be? Electric are not my strong point BTW

My first question is why does it have 3 horns? Everything Ive ever worked on only had 2 electric horns (high and low, air horns are a different ball game). After that make sure all 3 horns are wired to the same power source and have good grounds.

Frankly based on the fact that you have an extra one and its at a completely different location then the others Im thinking a previous owner did some tampering....

I did that and the two on the firewall didn't work.
