Kleinn 730 Demon Train Horn Kit: Unboxing and installation of KLEINN SDKIT-734

Complete unboxing and installation of Kleinn 730 Demon Triple Train Horn, using the KLEINN SDKIT-734 on a 2021 F350. Installed in front with a small air valance (similar to Tremor). No spare-tire delete. Wired to up fitter switches so normal horn and air horn work separately, using normal steering wheel button instead of the supplied dash button. Air compressor and 3 gallon tank with coupling mounted in back. Too Loud, Too Bad!

I wish I lived near you, I would pay good money for you to install the horn in my f350. You guys did a great job.

Thanks 👍

I used to have a demon 730 great starter horn. I moved up to Nathan's and Leslie's.

Are those Michelin Defender tires you have on your white superduty? Beautiful truck and great video btw thank!

[@WhiteKiid34]

2nd relay. Is one of the yellows combined with the Red from the 6th uplifter switch? If so does it matter which yellow from the tank is connected with that

[@waynelight470]

Looking for the part numbers for the relays you added. I'm actually going to attach mine to a larger compressor/tank I'm installing.

[@mpshake]

Yes, the part number for the second (Doorman) Relay would be nice 😁👍🏻.

[@Superduty_59]

Go to any parts store and get one. It is a Bosch style 5 blade relay. I just got one yeserday at O'reilly for $7.99

[@patriotone755]

Really professional install. Well done and thanks for sharing.

Lol

Dammit... 2023 kit is out and I can't live with those trumpets hanging down. Tremor valence.

[@DennisSunga-nw8jl]

The 2 blue wires you connected and use from the factory horn, does it matter which ones goes on the top of the relay and the other in the middle?

[@PowerStrokeTechTalkwARod]

Brother, great video! Id love to chat about your install. If you ever need Powerstorke help, feel free to reach out 🫡

[@jfarrugia]

We need follow-up.

[@familyelements4805]

Thank you! My father in law is the brains behind the installation. I’m sure he’d be happy to help!

[@djweaver30125]

Can you explain the pinouts for the horn relay that you added?

[@familyelements4805]

The truck manual has schematics that show the wiring bundle and which color wires go to which switches.

[@djweaver30125]

@@familyelements4805 no I'm talking about the wiring of the relay that allows you to use the horn button for both the stock and the air horn.

[@familyelements4805]

@frankmarinojr3178 maybe my father-in-law can answer this

[@vancewilliamson5542]

Awesome video.

[@Rmacntosh]

🤣😂 Love it!

[@kevindick3754]

does it come with mounting hardware (brackets)

[@familyelements4805]

Yes, all the hardware was included!

[@kevindick3754]

Did you lose the ability to keep your spare tire under the truck?

[@familyelements4805]

Yes, the compressor is above the tire and the horns are in the front. Keeping the spare tire was a must for me.

[@kevindick3754]

@@familyelements4805 just to confirm, you are not able to carry your spare tire under your truck like you did before. For me i need to carry my spare tire

[@familyelements4805]

I do still have the spare tire under my truck after this installation.
