--save me the nonsense about how illegal or annoying these are! I think it's great.
Let me know how loud they are. I'm wanting to get some.

Nomansland I went back and read the original post. I didn't detect any arrogance or idiocy. Huh, must be me.
I like the laser idea!

Nomansland I like having an air horn. I've had them on several vehicles and never abused them but when you need to make your prsence known they are dam handy! Especially since no one pays attention these days to what is going on around them.
The problem, is the fact that people are so intolerant these days any legitimate honk of the horn is gonna get ya the finger! Oh well!

NorthEastJK Retested the horn lead at the horn, and indeed I got 12.4vdc.

Thanks for the help.

wickedyj95 The wire going out from the fuse box is supposed to have a 12 volt current that activates the horn . Just get your self a test light or multimeter to probe it while the horn is blowing and see if you either get light or right at battery voltage . You should be good .

NorthEastJK Does our horn have 12vdc lead?

I'm trying to use the horn to trigger a siren.

Ted_D I wish someone would make a laser that mounts on front of the jeep so I could just fry some idiots

One of my favorite things to do as well. I dont have a train horn though. I went with a air horn from an International dump truck. Not as loud as the train horns but a much deeper tone.

s3nt3nc3d I replaced my factory horn with a small air horn...yeah, it's not a train horn...but with all the idiot drivers on the road today, loud horns definitely serve a purpose. I like to make sure EVERYONE around knows when some idiot pulls out in front of me. It definitely gets the driver's attention better than my wimpy factory horn did as when someone pulls out in front of me, I hit the horn and watch them immediately jump and look back. Never got so much as an acknowledgement before...

Mike5087 I ran all my wires through an existing hole on the passenger side just below the glove box. May not be there in yours. PO may have drilled it himself. As for your other questions I do not know.

NorthEastJK Not to thread jack, need some quick assistance.

I am trying to use a 12vdc feed from the horn in my jk to power an aux siren when using the jeep on emergency calls.
Dealer says k19 is a relay. I can't find it.

Goal is to wire a 12vdc from the horn relay through a switch which will be off until the need for the siren arises.

Also, where is a good location in tge fire wall to drill a hole for a wire pass through?

HeadturnerYJ Friend of mine had a train horn set up in an old saturn we set up a couple times, then moved into an s10, basically the way we ran it was hot lead (fused) into the compressor, ground lead into a switch and then from switch to compressor, with a second button to activate the horn solenoid. his was not a kit though, all the pieces were torn off of various old big rigs, and the thing would fill tires etc...

So you think?

So, am I understanding this correctly? Buster only uses his train horns when he is travelling on the rail system and approaching a crossing! Ah, I see. DOH

Yeah, I too use my air horns (dual) when butt-heads pull out in front of me and risk their life jumping in my path. As would any trucker.

Mike5087 Haven't messed around with it today. Bears packers game all day today sad to say.... Gunna try and tackle it sometime this week if possible.
09-25-2011 08:17 PM
aelwero so... did we figure out the wiring?
09-25-2011 05:30 PM
Jma20a what do you plan on using it as an on board air system for? the tank is small and the compressor doesn't have enough power to refill the tank at a reasonable rate. i would say that if you are looking for an on board air system get a real one like this.
09-25-2011 05:06 PM
Mike5087 Idk I've been sitting on this money for something for the jeep for a while. Good thing about it is it's a ridiculous horn and also an on board air system.... So the train horn may get old, which i doubt bc i have a ridiculous sense of humor, but the air compressor will always come in handy. Take it as you will.......
09-25-2011 04:55 PM
Jma20a when abused train horns get boring quick, eventually a few months down the road you are going to say "i wish i spent that money on something practical for my jeep" and i'll put a George Forman guaranty on that one.
09-25-2011 04:17 PM
Mike5087 Yea I dont know if I'll try and put one on your jeep. You just might nor be cool enough for one haha!!
09-25-2011 03:05 PM
aelwero I think train horns are retarded too for the record, but I'll help ya install it if'n I can... it's your jeep just don't come to texas trying to put one on mine...
09-25-2011 02:22 PM
Mike5087 Well yea I intotaly understand. I know how ridiculous and idiotic the thing is. Love it. I may use it inappropriately but that's the humor behind it. To each his own.

it's like blue hair and skinny jeans buster... everyone has the freedom to be their own kinda retard

I've taken an angle grinder to my jeep twice for major surgery and it's got a whopping 16K miles on it... I've had several people tell me that it was stupid...
09-25-2011 09:08 AM
Mike5087 Thanks for the replies. Once I get in there an can take a look some of this will make more sense. Appreciate it.

As for you buster... What can I say, I expected to get some responses like that so I'm really not even mad. Actually got a good chuckle when I read that.

aelwero you can also eliminate the relay entirely... take your 12V supply line, run it to a switch, then to the compressor. Run the ground from the compressor to the pressure sensor on the tank, and ground the other line on the pressure switch...

same exact outcome, except that you're running the entire supply through the switch. Check the rating on the switch (15AMP, 30AMP, etc.) and make sure the fuse you put on the line is the same rating or lower. You don't want 30 AMPS running through a 20AMP switch... that's called a cigarette lighter

There are higher amp switches you can use also, push/pull types or red key shutoffs are great.

aelwero the relay is used as a dual function switch...

on the hot side (of the relay), at 86, you apply +12V using the accessory switch. shut off the switch, you got no 12V, and the relay stays open and the pump doesn't run.

on the ground side (of the relay), at 85, you apply a ground, which goes through a pressure sensor on the tank. tank reaches pressure, sensor opens, shuts off the ground, and the relay opens up for lack of a ground and shuts off power to the pump.

If that doesn't compute, ask very specifically what part you aren't getting and I'll try to Barney it up a little more

the relay should have the numbers 85, 86, 87, and 30 stamped or printed on the bottom... you can just run 4 wires off it to the right locations based on the picture and not worry about what they do or why they are there... run them as shown and they will work properly...

the solenoid is a totally separate circuit...
