Question 1

If i get the horn, solenoid, and the wolo tank, will it come with wiring and hosing for set up?

Accepted Answer

The horn came with a short piece of hose to go to the solinoid. You will need another piece to go from the tank to the solinoid.

Question 2

how long is the distance between the front and rear mounts on this?   the install instructions dont say. thanks!

Accepted Answer

The front mount can move but the standard distance is roughly 17 inches from the center of the back mounting hole to the center of the front mounting hole.

Question 3

Can we find a protective front shield or cover to avoid dirt to get into the horn ? Thanks

Accepted Answer

I’ve had other horns in the past and have been able to get online and find a cover for them

Question 4

Can i wire a foot switch for this

Accepted Answer

You can wire in whatever switch you desire. Push button, toggle, whatever you can wire.

If I remember correctly the switch is not included (or a basic switch was included that didn't suit my needs - I forget but 90% sure it doesn't come with a switch). I ordered a micro switch separately for a few dollars (less than $20 for sure) and custom mounted to the dash. My recommendation to anyone who is installing this sort of setup is to leave the stock horn in tact for State safety inspections and if a copper pulls you over and wants to check the horn for whatever reason. I wired the switch to the negative side (pushing the button connects to ground energizing the circuit - opening the valve on the air horn) but most instruction manuals out there (https://c.hornblasters.com/manuals/color/ah-s4-manual.pdf) recommend the button be wired to +12 VDC. Either way works just fine. Enjoy!

I bought this horn, the wolo valve+soleniod, a micro switch, and a VIAIR onboard air setup with 3/8 in. lines. I went 3/8 in. up to the valve which was a few inches from the trumpet (had to buy a 3/8 to 1/4 adapter for the wolo soleniod but you can get that at most any hardware store in the compressor / impact tool section). The faster you can get more air up to the solenoid the stronger and fuller the horn blast will be. So I went 3/8 in line up to the input side of the valve/solenoid and I kept the stock 1/4 in line that the trumpet comes with for the output side of the valve to the horn. The trumpet handled 225 psi from my system fine although the recommended levels are ~100 if my memory serves.

There was zero delay (buildup) from when I pressed the horn button to the trumpet blaring. Just talking about it is making want to install another one on my Jeep.
