Well in theory you would find the activation wire from the horn switch in the steering wheel somewhere in the wiring bundle. Cut that wire and run it into a two position switch. Of of one of the poles you run the other half of the stock wiring, off of the other you run the activation wire to the relay of whatever big horn you're using. There's probably a bit more than that but that would be the gist.

Let me look into it.

 

For ultimate flexibilty, that sounds like a GREAT idea. Another one from Mr. Spots!!

 

THATS IT im buying the train horn > its gonna be awesome and evil and scare the crap out of anyone that comes within 2 meters of my car. BAHAHAHAHHA. loll... once again if i bhad the money.

 

You can still get a lot of sound from a small air horn vs. a train horn. I was reading through a post someone on a motorcycle forum was making about the stebel nautilus compact dual air horn. He was getting ready to leave work (at Lowe's) and was installing his new horn on his bike in the parking lot before he left. When he was testing it all the people in the warehouse came out to see why there was a train in the parking lot. Sure it won't be as loud as a train horn, but there's really no need for something that loud. Advance Auto also sells a three tone air horn (w/ small compressor) for $30.

Also side note, do you have an alarm on your car? My old truck had a two tone air horn installed in it by a previous owner, as well as a security system. At one point when my brother still owned the truck the alarm either shorted or was activated (suffice it to say it went off) and was going off long enough that it burned out the compressor. Something to think about.

As to the horn switch idea, I have a question in to my electrical guy about how it could all work, and what wiring would need to be tapped. I'll let you know when I hear something.

 

no i dont have a car alarm on my car just the keyless entry... which sucks but oh well. sincei have the immobilizer im not too worried about people stealing my car. but that would be good. where do you go to get those horns? auto advance? what is that.... maybe ill loook at canadian tire to see if they have em haha

 

LOL.. i guess bush got his ******* in the oval office too.. lmao.. ok back on the topic...

i dont have an alarm.. i have a panic button though (useless). seems like a whole lotta wiring for something so simple. spots thank u in advance for all your help.

 

Advance Auto is just a US national auto. supply store. Canadian tire would be the equivelant.
