I want it to work off my marine battery thru a button I in stalled on the boat. I've installed it but when I push the button all it does is buzz. Please help me if you can, thanks!

It could possibly be the relay itself or the horn. To test connect power straight to the horn, if it goes off then its the relay if not then its the horn.
factory security does not have toggle switches as far as I know so it is probably an aftermarket system. Try one of two things, turn the toggle switch the oposite direction with battery disconnected. Reconnect the battery and try again, the horn will beep a few times when you reconnect. try starting. If that doesn't work, disconnect the battery and turn the key to the on position and reconnect the battery and the horn will sound but will go off get in the car and try to start. It should start and run normally. shut car off, then you should be able to return the toggle switch to the previous position If this happens again turn the toggle switch to the opposite position with the batterry disconnected and turn the key switch to the on position and reconnect the battery and start when started go see a service that installs aftermarket systems and they should be able to reset it security system Hope this helps
CHECK for bad grounding of horn itself, rust and oxidation may not allow it to ground, also try "jumping" a wire from battery to horn, if it blows horn itself is good, contacts inside steering wheel button may be bent flat, or wire bad..
the clicking sound you here is the switch get out a test light go straight to your horn have someone hit the button if your test light lights up your getting power next thing to do is to check ground use a ohm meter and check for less then .5 of ohm of resistance any more is bad and you should run a new ground if your still un sure hook the horn straight up to the battery and see if it will go off lol good luck!!!
Your horn circuit is very simple. It consists of the primary circuit, which controls the relay coil and the secondary circuit that applies voltage through the relay contacts to the horns.
The Horn fuse (10 Amp) in the engine compartment fuse block supplies the battery power for both the primary and secondary circuits. This fuse is haot at all times (regardless of the ignition switch position).
Battery power is supplied to Pin 1 of the horn relay. Pin one of the relay connects to both the relay coil and to the secondary main contact.
The ground for the relay coil is provided via the GREEN/BLACK wire through the horn switch. If the relay is clicking when you push the horn button, then the primary side of the horn circuit is working.
When the relay coil is grounded by the horn switch, the relay contacts come together (that's what makes the clicking sound) and supply voltage to the GREEN/WHITE wire that connects to the horn assemblies.
Check for battery voltage at the horn when the horn switch is pressed. If there is no battery voltage present, then the only thing it can possibly be is dammaged contacts in the horn relay or the GREEN/WHITE wire is broken between the relay and the horn.
If there is voltage present at the horn on the GREEN/WHITE wire, the only possibilities are bad horn assemblies or a bad body ground that is not allowing the horns to ground properly. A bad ground condition can be verified by running a jumper wire from the battery NEGATIVE post and connecting it to the mounting bolt at the horn. If this makes the horn work, then you probably need to repair your body grounds near the battery.
LOOK UNDER THE LOWER AIR DEFLECTOR FROM BELOW THE RADIATOR. IF YOU HOT WIRE CAR HORN AND IT WORKS.YOU HAVE TO REPLACE THE WHOLE AIRBAG IN STEERING WITH HORN CONTROL BUTTONS.YOU NEED TO DISABLE AIRBAG IN STEERING WHEEL WHEN REPLACING AIRBAG AND HORN CONTROL BUTTON PAD.JUST TURN OFF RADIO FIRST, THEN DISCONNECT REMOVE THE NEGATIVE BATTERY CABLE.WAIT 20 MINUTES BEFORE WORKING ON AIRBAG AND HORN PAD IN THE STEERING WHEEL.
if the steering wheel clicks when you push on the horn then the wiring from the horn pad out to the horn is good.if it clicked before you replaced the parts then you didn`t have to replace them.check the horn at the horn,with someone pushing on the horn pad tap the horn to see if it will try to work if so then the horn needs to be replaced if not then run a power wire from the battery positive to the connector at the horn if the horn works again the horn needs replacing.
If you have a test light, unplug the single wire that's plugged into the horn. Connect your test light clip to a good ground such as the engine block or even the battery. Then insert the point of the test light into the terminal of the wire that you unhooked from the horn.Have someone push the horn button and if the test light lights, you do have power to the horn. If it doesn't light, you might check the horn relay. Sorry, I can't tell you where it is in your Mazda though. If the test light did light up when the horn button was pushed, then I would suspect that it isn't grounded properly, or, the horn is defective. Try unbolting the horn and sanding off the rust that formed between the horn and where it mounts. Typically, horns are mounted to the vehicle's frame.
Assuming you don't have any other problems to deal with like a bad horn relay, you would want to intercept the horn signal wire going up into the steering column and wire that to the switch such that it gets grounded by the switch when you want the horn to honk. Since a toggle switch could be left on for an extended amount of time, I would think a momentary switch of even a push button type might be a better choice?
The horn relay is used to allow for large current flow going to the horn itself without forcing that same amount of current to flow thru the horn switch in the steering wheel for example, which might be easily burnt out without the relay's buffering effects. Even a large macho toggle might not be able to handle a horn's current if used regularly. The load for a raw horn is highly inductive (arcing,sparking) in addition to being a very large current draw of 10 amps or better, both conditions tend to make kindling of everything but the most robust switches. Those switches when you do find them cost the big dollar$.
You might just need a horn relay, they do have a lot of work to do - they are allowed to wear out occasionally considering their use.
