Subject: Horn Honk?

I have an UNGO MS2004 alarm and the only feature that I have never used is the horn honk function. My question is, is there a special way to hook up a relay to do that, or is it the basic way. The wire is a BROWN / WHITE wire and it is negative output. Would I connect it like this? 86 = BROWN / White wire from brain 85 = Ground 87 = Constant 12v fused 30 = Out to horn wire. Also does anyone know if I have to do the programming from inside the brain or with the remote for this alarm? Such as setting Pulsed or constant. Any help appretiated, thanks Sandro -------------

Every vehicle horn circuit I've seen needs only a ground. Tie the BROWN / white directly into your horn wire. ------------- Chuck

Some horn wires require a relay because it is a high current negative output. Acura's require a relay to boost the signal from the alarm/RS unit.

Jeff, I have a 1995 Acura Integra with a Clifford 9000 installed on it. Is it possible that you can send me instructions on adding both a hood/trunk pin? I'm also interested in how to wire my horn to the Clifford 9000 as well. If you can help, it would be greatly appreciated. Thanks! Ernie

It's for my brothers 1990 dodge shadow. The wire is blk/Red that I have to tap into. So is that relay set-up the correct way? I have to use a relay with this alarm.

Ernie, READ the Diagram I did for 92 INTEGRA should be the same with your 95 Integra https://www.the12volt.com/installbay/display_topic_threads.asp?ForumID=5&TopicID=5629&PagePosition=1#thread ------------- THE ROOKIE!~

hot_shot_guy, connect the negative horn output from the alarm directly to the horn lead in the steering column. No need for a relay. However, if you want to use a relay, connect the alarm output to 85, ground to 87, 12V+ to 86, and the vehicle (-) horn lead to 30. If you need to send 12V+ to the horn at the horn, connect the alarm output to 85, 12V+ to 86 and 87, and the vehicle (+) horn lead to 30.

So will I run into any problems if I just run the horn wire from the brain to the horn wire in the steering column? Why in the manual does it say I need a relay then??

If you were to connect it to the positive horn lead as you described in your original post, you would definitely need a relay, but if you were throwing 12V+ to the lead in the steering column, the horn will never sound. You need to supply ground to this lead which BTW is going to the coil of the horn relay :) If the output from your Ungo is extremely low and does not sound the horn when used without a relay, then you'll have to add one as I described above.

O.k. thanks 12volt, I'll give it a shot with just running the horn wire to the steering column then if that don't work, i'll hook up the relay to send the (-) signal. Thanks for your help.

joelr7309, Sorry to bother but I'm new to the forum as you can tell and Im kinda confused right now.  Am I supposed to get a Relay, and will it show the terminal numbers as indicated in your diagram?? Or should there already be a relay somewhere in the vehicle? Can I get this relay at any auto-parts store? Need Help!!!!!  Ernie

Well What me and Cpgoose did to have the horn and the alarm to go off when triggered is, like the diagram, WE both have a Viper 550esp, hook up the siren red wire to the diagram show, jumper the wire, and do the relay like showen, whats cool is that when you press arm/disarm, it just chirp without the horn, but when triggered, both goes off and really loud, you need 30 amp relay, 2 prong flasher. you can get it at a auto store or PEP BOYS or Radio Shack, JUmper 87 and 85 to ground, 86 (+) to siren 87 (-) to ground 30 (x) flasher 85 (-) ground too Flasher (L) to (+) horn 95 INTEGRA | Horn Wire | Blue/Green (-) | Steering Column |

look for the Horn near the steering wheel, there should be 3 wires, look for the blue/green, use a Digital Meter and look for a (+) connect (L) to that

joelr7309, So I would follow this same setup even though I have a "Cliffoerd 9000"?

yes, depending on what the horn takes, If its a (-) output do vice versa with the relay

Let me take that back, It's a (-) neg output your looking for, It should be the same with you syndicate2323, if you have the same a alarm, what type of car are you trying to put it on?
