I have an aftermarket alarm system in my truck. When the alarm is activated,  it sends a pulsating - (Negative) Signal to my factory horn. It sends an "On - Then Off Signal" I want to add an electric air horn to the output signal from the alarm. After the alarm sends out the Negative pulse and honks my factory horn, I want it to then honk the electric air horn. In other words, alternate between the Factory horn, then the Electric Air Horn. When the alarm is in the neutral pulse after honking the factory horn, I need it to then honk the electric air hor. Can someone grive me a type of relay or a wiring diagram to hook up to this pulsating Negative signal to acheive this outcome?

Sure. I need the year-make-model of the vehicle and the make-model of the aftermarket alarm,

Why is that necessary? the horn output signal from the alarm is (-) 500mA. This wire is hooked up directly to the (-) horn output wire for the truck. It honks the horn "Honk, pause, Honk, pause, Honk, pause". All I want is something that when the negative signal is neutral, I can sent a (-) or (+) signal VIA relay to the Air Horn.

Does the alarm have a siren output along with the horn out wire.  If so this can be done with a couple relays.  Going to give this a shot without having to draw a diagram.

Relay 1  30 to the battery via a 15 amp fuse.  87 to the siren and also to 30 and 86 of relay #2.    Relay #1 continued, 85 to ground.  86 to siren out wire of alarm system.   Wiring for relay #2  30 is already connected,  87A to Compressor.  86 is already connected to power.  85 to negative horn output wire from alarm along with the horn wire of the vehicle.  

Any time the siren is going off and the horn is not, the air horns will be.  If the air horns are not going off, the horn is.

Let me know if you need the picture.

Yes the alarm has a siren output, but I do not want alternate the siren output. I only want the alternate the horn output. When the alarm is honking the alarm, the horn honks then stops, then honks , then stops. When the Horn is "Not honking" the factory horn, I want it to honk the electric Air horn; so there is a constant honking of horns. What I want is Factory Horn, Air Horn, Factory Horn, Then Air Horn ect.....

Thanks,

LC

Well, there is one wire down. Now I will need to know if the alarm has a GWA output?

I'm sure it does.
