wiring a new aooogah horn in 1927 Ford

Sorry, I posted this earlier in the wrong area! I am trying to install a aooogah horn in my 1927 Ford Roadster. The car has an aftermarket wiring harness with a fuse panel that has a connection for the car horn and sitting behind the connection is a 40amp relay that clicks when you ground a tester light to the car and touch the terminal on the panel. Can I take a wire from that terminal to my push button switch I am using and then take another wire from the other side of the switch to the positive side of the horn and then groung the negative side of the horn to the frame of the car? This is what I had planned to do until I began to read another forum, that says to run ground to your switch. I had purchased a relay to install, until I found the wiring harness already has one. Please advise for the proper installation. Thanks for all the help, dandeto

negative

The horn button controls the ground side relay coil. When you press the button it closes a contact which completes the circuit to ground thus energizing the coil of the relay. The other side of the coil is fused + at all times.
The contacts of the relay close whenever the button is pressed completing the + circuit to the horn.

Aoogah horn now working

Thank you for the information. Once you take a good look at it, it works well. I ran a positive wire to the horn and took my wire from my 40amp relay and ran that to the push button switch and then ran the other side of the switch to ground and everything works great. Thanks dandeto

horn

It might even do more. When you hook the Positive terminal of your battery to ground, and the Negative is hot, to most people that would be backwards, of course some people dom't know positive from negative.
