Connecting air horn to auxiliary switches

[Kilobravo]

I would like a little assistance in installing an air horn with compressor.

The compressor draws 17amps and I'd like to know if I can connect the horn directly to the wires for aux 6 using the relay supplied with the horn or do I have to connect the relay directly to the battery and then use the aux to switch it.

Aux 6 can handle 25amps. You can go direct. Aux 6 is the only aux option that has a paired ground otherwise you’d go to the battery.

And I imagine your wire runs will be short so no issue IMO

Also, you don’t need the horn’s relay. You actually cut it out of the harness as aux 6 is relayed already.

Ok great that sounds good, so all I need to do find the yellow wire and yellow/ black wire and hook up to the positive and negative of the horns compressor.

Yup. And it’s taped between the radiator and the left side of the battery. It looks like a little mini fuse box and that’s where all the Aux Relays are. You shouldn’t have to touch those.

Ok thanks for your help.

I’m gonna need a video of this horn firing off too! Happy to help.

Be aware that your electric motor will have a MUCH higher initial surge current than its rated 17 amps. I personally would want to protect my factory wiring from that excess current, I would install a separate 50 amp relay, and just use one of the other Aux switches to control it. Use heavy short wires from battery to relay to horn, for example 8AWG, with an inline fuse in the positive cable. What does the horn instruction manual say about this? That should be your main guidelines… did it come with a wiring kit?

if you want the horn to work off your steering wheel pad, instead of sounding CONTINUOUSLY, you will have to get creative.

I really like the stuff from this place, they make high quality, reliable products.

The horn came with an 80 amp relay and a 30 amp fuse and it gives instructions on how to connect the relay to the battery.

bro if this is a seriously question you should be taking it to an auto-electrician to install......

Which kit did you purchase?

Nothing fancy just a $35 kit from Amazon. It has a 200w compressor and 2 horns.

Got it. Good luck, let's hear it once installed.

I am no expert in vehicle maintenance, nor am I an electrician. But I can tell you that I just had two of these installed over the weekend, and they are super loud. I still have my regular horn, and both of these are connected to my first Aux switch. Tankless as well....

Kleinn has two kits they list for the last Gen but American Trucks has them listed as working for the next Gen as well. These are super expensive but I'm curious if the bracket will fit in the next Gen. I installed one on my Gen 2 F150 Raptor. https://kleinn.com/products/direct-...-2019-2023-ford-ranger?variant=44387305881762
