I have BigBF quad horns, I guess that's what you have?
Once, on a trip, one of the un-loomed wires I had added
to my accessory fuse box shorted out. When I figured it
out and cobbled together a fix...

... the horns blew continuously. I'd wired them up blindly following
BigBF's instructions. When Gordon demanded to know "why the
&^%$!! did you do it like this? ! ?" I didn't have a good answer

...
Anywho... later, at home, I stripped out the BigBf wiring that
I didn't understand and wired them up like I thought they
ought to go... all four grounds to ground and a relay makes
all four hots hot... they work great now...
