Air horn and foot pedal switch wiring:HELP

So I’ve already got a Gampro airhorn wired up to my stock horn switch. I wanted to do something different this time, install another Gampro airhorn, but instead of tapping into my stock horn, I wanted to install a foot pedal switch, similar to the ones in fire trucks. My problem is the foot pedal switch has 3 wires: black, white and a green neutral. The 12v compressor has 2 hookups. I’ve tried it hooked up to a 4-pin relay, nothing. Hooked the + of the switch to the battery and tapped it to a + coming from the compressor and the switch did nothing, the horn was going off continuously. Quite a learning curve from the previous install I did. Any help is appreciated

 

Ahhhhh . . . . Why?????

G.

 

Are you really trying to wire an air horn to your buddies brake pedal?

 

You could hook it up to your brake lights. And have it go off every time you put your foot on the brakes. It's a great prank if you ever do it.

 

have you seen the YouTube videos when they does this to someone. It’s pretty funny

 

Nahhhhh, this is a whole other pedal. Trying to mount the pedal somewhere near the dead foot rest

 

Here’s the horn and the foot pedal switch

I want one on a switch and mount it under the cab pointing to the left and right to give a heart attack to the jackasses I get next to I see on the phone.

 

Thank you, this damn switch has been irritating me all night, time to take a break for now. Does it make any difference that the switch is single postion, double throw and normally open?

 

The horn I have tapped into my OEM horn definitely scares the shit out of people, especially in tunnels

 

That is a SPDT (single pole double throw) switch. The 3 wires are NO (normally open), NC (normally closed), and COMMON. Figure out which are NO and COMMON. Those are the 2 wires you want to use. Make sure you insulate the NC wire.

 

Gotcha, guessing NO is my positive and COMMON is my ground

 

NO to the relay. COMMON to ground, IF you are using the diagram I referenced.

 

Not understanding why people gotta do this kinda shit...……….The horn wasn't loud enough? I used my horn twice in 6 months...…...

 

Last time I checked my truck was in my name

 

Needs more attention

 

Also being most of my commute to work is through congested highways and city streets where no one uses signals,mirrors, etc

 

And I drive through Deer country. See about 5 deer a week. To each their own, your truck, you paid for it. But the horns not the problem...……...

 

Oh I’ve got the sun gods on my side too but during the day it doesn’t cut it
