Hella E1 Airhorns

*bump*

Anyone? Is this just a matter of piggybacking off the original horns? Should I bypass the two original horns entirely, use one + the hellas, or use them all? Any suggestions would be appreciated.

Kpaske,
when I installed mine, I disconnected the original horns and used the existing wiring to hook them up. Since there is already a relay in the factory wiring, there is no need to install an additional relay. I removed the passenger side horn and fabbed a small braket to mount both horns on the factory mount. This positioned the horns close together facing down just behind the cladding. It was a struggle to mount them there and took some acrobatics - but easier than removing the cladding - hope this helps!

I want to add a note - I installed my triple air-horns a few weeks back, and they sound awesome. Perfect loudness - better than stock, but not a train blast - and different from anything I've heard, almost like a Ferrari, but not quite.

I understood that putting airhorns on vehicle other than a diesel truck or similar may be illegal in some of the more anal states, like California or New York

I think I can field this one, for Californians at least...

CVC§ 27000 - Horns or Warning Devices
(a) Every motor vehicle, when operated upon a highway, shall be equipped with a horn in good working order and capable of emitting sound audible under normal conditions from a distance of not less than 200 feet, but no horn shall emit an unreasonably loud or harsh sound. An authorized emergency vehicle may be equipped with, and use in conjunction with the siren on that vehicle, an air horn which emits sounds that do not comply with the requirements of this section.

Which means that they are not illegal, but "unreasonably loud or harsh" is at the descretion of the officer. You could always fight it in court especially if it is close to the tock horns decible level.

And while we are at it, you would more probably be cited for unnecissary use:

CVC§ 27001 - Use of Horns
(a) The driver of a motor vehicle when reasonably necessary to insure safe operation shall give audible warning with his horn.

There ya go...

And one caveat... This doesn't mean that your city and/or county doesn't have an ordinance prohibiting their use. Check with your local agency for an answer to that.
