Just a quick FYI - I'm not new to this forum, I have been inactive for a while and I guess since I have been for a while, my username isn't active anymore so I had to create a new one. It used to be RichB. Anyways.
What I am trying to accomplish is this:
I have a 2013 Hyundai Sonata with a factory alarm/keyless/remote start. The factory "siren" is just a rinky dinky Hyundai small horn. I already swapped those out with some horns from a Ford truck so they are actually loud. What I want to do is actually make the pulsed 12v output that makes the horn honk-honk-honk, etc to a constant 12v and hook up an alarm siren to that so it's a real alarm siren with all the different tones. It's a simple 12V DEI 6-tone alarm.
I wired up this relay configuration today:

The issue I am having is that I don't want to have to install a switch in between the ground to break it. Once the alarm is activated, the output from the relay is getting 12v and once the alarm is deactivated the factory lights stop flashing but that wire on the relay is still getting 12v unless I disconnect it from 12v or ground.
Is there a way to wire in another relay that will somehow break that ground so I don't have to do anything manually? I'm fairly familiar with relays but this one has got me baffled because I've actually never done this before!
Pleae help!

i know there is also this diagram

except the input on the left relay is negative, I need the input to be positive so what would I need to switch on these 2 relays?

after a little more research. i think this is what i need to do. basically use a 3rd relay to convert the positive trigger into negative and then use the first 2 relays and go from there. i'll give it a shot tomorrow but if anyone knows of anything else to use less relays or other alternatives, please let me know

Your last diagram will create a latch, but you only need one relay to create a latch with a postive pulse and a second relay to break the latch with either a positive or negative pulse. I'll draw up a diagram today and post it here when I finish.

what I found out is this.
right now i have this setup on my car:

i have a momentary push button switch installed (hidden where only i know where it is) that when the factory alarm is going off, i can disarm it from the remote but the DEI sirens are still going off because it is still getting 12 volt so i hit the switch to break that feed from the battery. when i disarm with the remote, that factory wire does not send another 12volt pulse. it just shuts the alarm off. now unless i am missing something somewhere, i don't think what i want to accomplish can be down without a switch to break ground or 12v somewhere.

You could use the door unlock motor leg to kill the latch when you disarm it.
Unlock Motor      red      driver kick, white 56 pin plug, pin 11

i'm not sure where you got the wiring info from but that's not right. the wiring for a 2013 sonata SE 2.4 w/ dimension sound/navigation is:
Driver Mtr Unlock     GRAY (REV) AT MOTOR IN DOOR
Driver Mtr Lock WHITE (REV) AT MOTOR IN DOOR
Pas Mtr Unlock PINK/BLACK     (REV) AT MOTOR IN DOOR
Pas Mtr Lock BROWN / ORANGE     (REV) AT MOTOR IN DOOR
none of these are positive/12v so i don't think i can use the wires
