2nd Gen Non-Engine/Transmission Hadley installation

[John Berger]

I just bought a used Hadley rectangular horn. It's one of the big boys, an Ambassador, I believe. Since it won't go under the hood and I really don't want to drill up the cab roof, I was thinking about the passenger side frame rail. Has anyone ever done this? Are there any special parts needed to install there? I don't have a kit for the horn. I plan on using a compressor system. When I order a kit, what do I want to make sure is included for a complete install. TIA

see if it will fit on the cross member right under the intercooler and radiator, mine did, also keep your air line as short as possible between the tank and the horn... ... ... ... ... ... ... Kevin

simple system

you need a horn, tank, solinoid, airline, and compressor, then just run a jump wire from the solinoid to one of your oem horns, this way the toot is at you wheel and fingertips ... ... ... ... ... ... ..... or your FIST if its an idiot driver

hadleys are nice but i would rather have a train horn like some of the big boys have lol thats sounds neat, not to mention get your attention But all i know is i hate my CAR horn on the big rig

Save a few bucks......

I got a compressor from wal mart for $10. It works great. The only thing I had to get was a pressure switch to make it work automatic.



J. C. Whitney has all the parts. Solenoid, Pressure switch & tank. You can get air brake line from napa and it will work with regular 1/4" compression plumbing fittings. All will probably still run you $100 or so.



Any questions feel free to ask,

The Ambassador will fit on the cross member, but barely. I may zip tie it up top on the driver's side, but at least I have a couple plans of action. Thanks for the tips and I'll be back if I need anything.

If you use a solenoid, remember to check it periodically. My horn stopped working yesterday so I took it apart and found that water build up in the solenoid had caused it to get stuck closed, cleaned it up and now it works great.

I poked my Ambassadors down from about the injector pump to just level with the front crossmember, aiming under the bumper. Tied 'em in with BIG wire ties. I put my tank on the back of the front crossmember, and my pump on the fender well below the master cylinder. Everything's accessable, the horns are easy to remove for maintenance. They don't pick up water, and with the sound bouncing off the road in front of me, no one ignores them!

By the way, train horns are common as flies down here, and if you ask me, they don't sound cool, just high pitched and out of place. If you want pictures, e-mail me at -- email address removed --

Here is a picture of a Hadley Ambassador stuffed in my truck. Attach with zip ties, not bolted down.

That's stuffed alright

Your suggestion or jsimpson's suggestion are probably the way to go. I have more brake lines and the clutch slave cylinder to consider, though. Workable. Tight, but workable.
