How can i hook up my horn to my factory alarm to make it beep when i arm the system like on the 5th gens? if this is somewhat easy i would like to attempt this cause during the day i can't tell if my system is armed without looking at the turn signals to see if they flash. i seen the mod to make your alarm beep in the how to's, but i want to hook it straight to the horn.

 

Yes you could do that....just find the alarm circuit, and find out which wires activate the lights (just lock/unlock a few times, probing each wire). Then you will need a bit of wire and an automotive relay. Run the light coming from the blinker tap to the trigger pin on a relay, and wire the relay in with the horn and there you go...
