After almost getting in to an accident on highway that put my life in danger because an old cricket couldn’t see me and didn’t hear my horn I decided to get a good quality horn ASAP. Sound easy just buy and install – not so fast. There are bunch off different horns out there, but when I tried to search this forum I found only few threads that are at list few years old with no detailed info which and how, thus it is the main reason for this thread.
Nice air horn cost from $300 up to $500 but I did not need expansive train bluster, all I wanted quality budget horn. So after looking around without success I went to check reviews on Amazon and a little bit later I ordered this one:
Amazon.com: Chrome Trumpet 135db Air Horn Kit w/12v H.D. Compressor Plug-n-Blow: Automotive
Reasons:
- Good price for what you get, under $60 shipped
- made of metal with chrome vs. plastic
- do not require additional air storage tank like others,
- as loud in dB at list on paper as much more expansive more complicated to install horns
- the set has everything you need with exceptions of wires, in line fuse holder and quick connectors.
- Installation do not require having pro electrical skills just connect everything according to supply wiring diagram
- On the top of that our trucks happens to have perfect spots which makes easy to install this kit.
It took me a while to find these perfect spots under the hood for the horn, relay and compressor, but after I had everything I need the mounting and wiring was a flash.
You need: 3 feet of 12AWG wire, one 30Amp/12AWG fuse holder, got mine at RadioShack - $3, pack of male/female connectors at RadioShack for $3, wire strippers to make wire connectors.
Picture #1, shows installed horn, stock horn connectors, compressor, fuse holder.
Picture#2, shows how the horn is mounted. The holes are already there.
Picture #3, compressor mounted. The hole is there you just need to find nut that fits inside the compressor frame holder. On the other side I used bolt, locker, washer and one more nut to lock everything together. Also you can see relay bolt.
Picture #4, relay mounted. The nut is there you just need to find bolt that fit there.
Picture #5, shows relay and how I connected relay and compressor grounds to the frame.
Picture #6, one more view of the relay and fuse holder.
Picture #7, blue wire at the top that comes from relay connector 85, plug it into one of the existing stock horn connectors.
Picture # 8, wiring schematic that came with the kit.
I took the stock horns off. They are like plug and play, unplug the wire connectors and take out the bolts and they come right off. Mount trumpet, compressor and relay. Connect everything according to diagram. If you take the battery it will make the job much easier, I was lazy and didn’t do it. Also I used 25Amp fuse, 15Amp that the schematic call for not enough. My 15AMP fuse blown the next day right at the moment when I need it the most. Not fun I was angry like hell.
The tone and loudness of the horn sound is very close to 18 wheeler. A bit deeper would be nice but not big deal. I always smile after I use it.
