I am trying to install my Hella Dual Air Horn kit. I tried to follow the directions for wiring it, but it failed. I dont know specifically how to wire it up. is there anyone that can talk me through it, or post pictures of the install, or the final product? I would realllly appreciate it! Thanks

hey did you ever get you horn wired up? If so how do like it and how does it sound. I was thinking about getting one to replace my weak oem.

 

Go to the12volt.com, there are wiring schematics there. There's just 1 relay unless you want to do something fancy. If the horn doesn't work it's probably due to the pins on the SPTD relay being connected to the wrong wires. I'd post instructions but it's Superbowl Sunday, sorry

As far as the horn are concerned, the sound is loud but not as loud as I thought it would be. But if you want the real deal of a train horn, be ready to shell out 300 bucks and have space for a compressor. There's also a slight delay due to the air travel but not that big of a deal.
