What is this kit http://www.hornblasters.com/products/details.php?i=hornair-540-horn-air-system missing to run a k3la on it?? i see it doesnt have an air valve but what else?? thanks for the replies
ptc on each side of valve, some tubing and a ptc fitting for on top of horn, it looks like it has everything else, besides valve as you mentioned.
if i missed anything someone will mention it im sure 
Ummm, maybe an air guage. Maybe a horn button.
Oh yeah, and it needs a super sweet bracket to mount the K3, but I’m sure you’ll make one & show us…Lol
Bryan: I have no idea what ptc is lol
ear2ear: I was looking thru the forums and saw a grip style button, that would be sweet http://www.trucknvans.com/ProductDet…ctCode=PL-SW19
Bingo. I’m getting one too. Mine is ‘rigged’ right now so I can roll with it in my lap.
You probably saw mine on the forums from a few years back … I enjoyed it but it was way to accessible… I drove with it in my hand and sometimes thought i was in a jet fighter… Only thing missing was explosions when i hit the button. hahaha
Push to connect fittings is ptc
we call those ITF’s (instant tube fittings)
