Horn Honk/Trunk Release

can someone tell me how i can add the horn to my alarm. i would like for t to honk when i am and disarm as well as honk when the alarm is triggered. i have a 92 olds delta 88 with a hornet 553t with remote start alarm system

Are you talking about the vehicles horn or the alarm's siren? If you want the horn to honk whenever the alarm is arming/disarming and sounding then you would need two relays. First relay would be: 85 siren output from alarm(you can still leave your siren hooked up), 86 ground, 30 ground, 87 output to 30 of second relay. Second relay: 85 parking light from alarm, 86 ground, 30 output from 87 of first relay, 87 to negative trigger for horn. This will honk whenever the siren is on, when the lights flash. If all you want is the horn then you would just use a relay on the siren output(converting it to negative) and use the output to trigger the horn, and you would have to program the the siren output to be chopped.Certified Security Specialist

do i run two wires from 30 and 86 and tie them together with a fusable link?

i am adding a trunk release to my alarm. i want to use the auxillary button on my remote to open the trunk. the alarm is a hornet 553t with remote start and the three wires coming from the aux harness are gray/black, light GREEN/ black, and violet/black all negative. which one of these wires do i hook up to the trunk release

on a car i had my horn would honk once when i armed twice when i disarmed my alarm and would go off along with the siren if the alarm was triggered. is there and way to make this happen with a hornet 553t alarm with remote start. i am installing this on a 92 olds delta 88

The RED / white wire in the main harness is usually use for trunk release. Its negative output. If you need a positive output, you will need a relay.

thanks . how would i use that wire in order for the auxillary button to work
