Wiring air horns to factory setup

Ok tundra Gods this my first tundra I have ever owned and I’ve done a lot of work on here but the last major thing I’m trying to figure out is how to wire my air horns to the factory setup using everything that came with the Air horns without going into the steering wheel....

 

Use a relay with the factory horn wire as the control side. All wiring will be done in the engine bay.

 

Which one is the actual horn wire to use the passenger side had one wire and the driver side horn has two wires

 

Welcome from NY.

 

Thank you I have had a lot of questions about the tundra and kinda figured it out on my own...This one is really kicking my butt lol

 

Both horns should be grounded through their mounts. The plug in the driver side horn has 2 wires attached. One is inlet from the horn circuit, the other is outlet to feed the second horn.

Edit: both wires in the plug should be attached on the same connector.

 

Are you wanting to run only air, or have the option to switch between air and OE horns?

 

Welcome, which horns are you going to install?

 

As the previous poster mentioned, you can simply use the wire going to the stock horn as the "control" wire (low amp) for a relay. When the relay feels the voltage from that wire, it should open its switch for the high amp side to run the compressor.
