Today my alarm siren went. I plugged a door speaker to it
And it worked, I wanted to wire the alarm to the facotory horn.

I was wondering if I could just extend the alarm siren wires and wire it to the factory horn with no problems.

good idea.

 

it wont work...you have to add a relay because the output on the alarm is not strong enough to sound the horn...

 

Thanks
So just a relay and it will work? So my horn will work by pressing the horn Buttons and still work for my alarm. It won't fry my alarm brain or nothen...

 

no it wont burn anything...if you add a flasher also it will make the horn turn on and off...if you use the relay only the horn will stay on the whole time until the alarm turns off...

 

How about you start with MM&Y of the car, many if not most car horns are already relay driven.
Also a make and model of alarm will help, some alarms have a horn option, no flasher needed. 94
