Train Horn Install - tC

[Phlame217]

I'm fixing to purchase a train horn and am trying to get ahead of myself by getting everything together for the install. I plan on installing a secondary momentary toggle switch next to the cruise control to trigger it and that wont be a problem at all.

What I need help with is the wiring for the compressor for the air tank. It needs an accessory line (a power line that is only on when the key is turned on or to accessory) to draw a 16 amp load from.

My original thoughts were to split my 0 gauge amp line, but that would drain the battery since the compressor doesnt have a remote turn on/off like the amp. Any ideas?

If u show me what ur getting i can tell u which way to go on the wiring but i need to see what ur getting :kid:so i can tell u how to wire up a relay ...http://www.scikotics.com/forums/showthread.php?t=24647

i'm not quite sure i understand your question, but i've installed a train horn in my xB so i'll try to help.

if you take a volt meter to your fuse block, you will find some empty slots (unless you've already tapped them) that are only hot when you have the ignition switched to "acc". if you plug the "12 VOLTS" wire, on the suicidedoors.com wiring diagram, into one of those slots, your compressor will not drain your battery as long as you put the relay between the power supply (ie your battery) and the compressor. that's what the relay does, it only lets power go through it when the ignition is on.

sorry if that wasn't what you were asking or if my answer didn't make any sense.

oh and as for the toggle switch, i have another suggestion; i ran the hot wire from my train horn valve to a switch in my center console and then to my stock horn under the bumper. that way when the switch is on, the train horn blows when I press my steering wheel horn button and when the switch is off, my regular horn blows.

here's a video:

Sorry, I guess I mistook the listed part of the "pressure switch" as the button pressed to sound the horn, but I guess its the relay so to speak. Could I not go ahead and split my amp line since it is plenty big enough to support the 16 amp load and then either tap the amps remote turn on from the stereo or run the line as previously mentioned into the fuse box.

Here is a link to the horn I'm getting: http://www.hornblasters.com/products/details.php?item=HB4H20GCC

Also, I was trying to figure out how to the thing you did vegan, but i was a little confused. Did you tap the + wire for the horn so when the circuit is complete (by pressing the horn) the voltage also runs to the solenoid and then just put a swtich in that line to control if the train horn is live or not? So technically both horns sound at once?

use a relay, use your 0awg for power, or run a new line to the battery (my choice) and then find a accy line in the car and use that to turn the relay on...check out the12volt.com for how to wire the relay.

Phlame, when you get this thing going let me know because I want to hear it. We will be at a show in OKC in 2 or 3 weeks I think.

i agree. :up:

exactly! and yeah both horns sound at the same time (my stock horn always sounds but you can't hear it all when the train horn blows.) and i just switch off power to the train horn solenoid when i just want my stock horn to sound. i do it this way so i've got the train horn for traffic situations when i just want to hit my horn button when i'm about to get ran over by soccer mom in an SUV on a cell phone. the switch is just to be legal in Oklahoma (and most states).

U can use ur zero gauge would be fine ur compressor doesnt draw alot of current /run u a another wire to ur ignition for the switched wire make sure u fuse it .

ur relay needs to wired up like this

Pole 87 =needs to have a 10 gauge goin to ur zero gauge.(put a fuse on this wire at least 30amp)
pole86= is goin to be ur ignition wire coming from the front .(fused with 15amp)
pole85= is goin to be goin to ground (metal on car )
pole30= is goin to be the wire going to the compressor.
pole87a=is not used tape up the relay after ur done .
After that ground ur compressor and u ll be done.

any more questons u can pm me.

exactly what I was going to say. Depending on where you put your relay you could use the 12v (constant) wire at the ignition harness instead of hacking up you amp power cable and also get ignition power right there too.

Im picking up a fuse block to split the 0 gauge into two lines and then I'll also get some 10 gauge wire along with a 30 amp fuse. Should I use like 22 gauge wire for the ignition line? The fuse wont be an issue.

Thanks everyone! I will be picking it up either tomorrow or next friday and will be installing on a saturday. It should be ready for the hot asphault show in oklahoma.

U wanna use at least 16gauge wire for the ignition wire.

[HyPnOtIk]

WOW this will be loud !

[Spock]

make sure to fuse the ignition wire. yeah and use at least 16-18 gauge.

Another question, I am looking to get a little excess fun out of this so I am looking to wire the horns solenoid switch into an accessory port on my alarm.

I have a Viper 5000 alarm and there are 5 open accessory ports (typically for trunk, lights, etc) that a diagrammed as outputting a 200 mA (-) current.
For example:
http://img404.imageshack.us/img404/8022/possiblehookupvm9.th.jpg (http://img404.imageshack.us/my.php?image=possiblehookupvm9.jpg)

Or would the 200 mA current be too small to trip the circuit, and therefore qould require a relay. The install manual for my alarm says if it exceeds 200 mA, a relay is manditory.

[Phlame217]

NM: I got to reading the solenoid switch circuit require a 5 amp fuse which means to me that it probably uses a 2.5 amp load or so. Now i just have to figure out what kind of relay to get for it.

I think this relay would be overkill, but it is better to overkill and fuse it than to underkill and blow the relay i suppose
http://www.oznium.com/relay40
From deriving previous info, i presume:

Pole 87 =Run a line from the fuse box to here (fuse with 5A as specified)
pole86= Line from the alarm box fore the remote activation (fuse with 500 mA since the alarm outputs 200 mA)
pole85= Ground
pole30= Run the line to the horn circuit on the solenoid side of switch to allow override
pole87a=Not used, so tape.

86=line from the alarm but its negative(which means ground) already that what will trigger the relay shut.. U can also put ur on/off switch on that wire so u can turn ur horn on and off cause u can tap this wire on to ur horn wire in the steering column.

85= is gonna need 12volts too u can put both these relays back by ur zero gauge just use that for ur 12volt power. the relay doesnt care about the amps cause it will draw up to 30amps and be fine.

Ur catchin on good tho

[Phlame217]

Im very visual so let me paint this out lol...
http://img170.imageshack.us/img170/1429/setup1an0.th.jpg (http://img170.imageshack.us/my.php?image=setup1an0.jpg)

Would that work? The only problem I see is the the relay wouldnt flip when the horn itself is tripped because the gound will only be active when the alarm is triggered?

And would I put the switch on the red line from the horn or the black line from the amp?

Also, would i need to switch the alarm wire to pole 85 and the horn wire to 86?
Along with this quesiton, the relays i got off of oznium dont have a diode. Should I put one in the line somewhere?

[madmaxbb]

U Can Hook Ur Alarm Wire And The Horn Wire Both From Ur Car Together To Pole 86 They Both ARE Negitive Ground Tirggers . HOOK 12 VOLTS UP TO 85 AND 87 COMIN FROM UR AMP WIRE(0 GAUGE)JUST FOR THIS RELAY
U Dont Need Diodes On It They Been Fine Thats How I Have 3 Horns Wired On Mine . U Can Put A Switch On The Wire Coming From The Car Horn To Turn The Train Horn Off Or On So U Can Just Honk Ur Regular Horn.

[Phlame217]

So...
Pole 85=12v Constant
Pole 86=2 wires: Alarm ground & the (-) from the horn[with switch]?
Pole 87=12v Constant
Pole 30=To solenoid

[madmaxbb]

YA ALARM OUTPUT WIRE THAT U ARE GONNA USE=EXAMPLE CHANNEL1OR 2 OR TRUNK POP WIRE . THEN U CAN PUT A TOGGLE SWITCH ON THE WIRE COMING OFF THE fACTORYHORN WIRE = SO IF U DONT WANT TO BE BLOWIN THE BIG HORN ALL THE TIME WITH UR FACTORY HORN

U CAN GET A SMALL TOGGLE SWITCH FROM RADIO SHACK/BUT IF UR ORDERING UR KIT FROM HORNBLASTERS IT WILL HAVE ONE THAT COMES WITH IT

[Phlame217]

Just wanted to let everyone know I got the horn(s) in yesterday, hooked em up today and they are INSANE! Thanks for the help!

[madmaxbb]

:up: no problem :Inclassable52:weres the pics tho come on lol :bangin:

[Phlame217]

A fellow club member took 'em and I am waiting for im to post.

[kris5597]

couldnt u run a wire off of the amp wire with another fuse and run it to a toggle switch for the power to the compressor and then get maybe a PUSH TO START button for the horn. or something of that sort. what i would do.
