Isn't there a schematic on the side of the relay's case?

It will show a coil and a symbol for a switch which is a line with an arrow and a contact that the arrow goes to when the coil is energized.
Maybe its the way I have the horn wired.
I have the - going to the frame. Then the + going to under the dash for the to connect to the relay.
Should it go + to constant power, then - to the relay?
or maybe I just have the wrong relay. the directions for the horn show a 4 wire relay.

Wow, I just went from the fuse block to the button to horn and to ground. I didn't use a relay.

Bruce, if you have a single OEM type horn, the horn button should handle that 60 watt load. That is 5 amps. Some ahhooga horns pull 120 watts which is 10 amps and would be a little more than most OEM steering buttons could handle, that is why the relay handles the amps and your horn switch only sees the load of the relay's electro-magnet, typically less than 1/4 amp. Oino, hope I was of some help. Just checking, but 3 terminal relays are generally used in vehicles designed for the horn to work without the ignition being on. So if I were using this type of relay I would supply the 12 VDC + from the fuse block on a suitable 20 to 30 amp leg. If you use the 12 VDC + from your ignition switch, then it will have to carry the full load which will cause it to crap out sooner than normal lifespan.
Ah thanks, I just have a cheap generic horn from the parts house, just to satisfy the Texas Vehicle Inspectors.

it don't work for me to
For the pos(+) I'm running it off a 10 amp fuse from the fuse box.
Have a new problem. When I use the horn on the column a couple of times it stoped working.
First time it happend, I found that the spring in side the springy thingy for the horn in the column was burnt and had no more springy to it.
So I replaced the spring and tryed the horn again. It burnt out.
