What size relay should be used with these horns? (what comes with the horns)
228975
All I did was use my existing connection from my single horn and split it to connect them into the hella horns.

I just use a regular 12 auto relay. 4 prong. Same as my HID kits etc. the one with the 30, 85, 86, 87 labeled prongs.

I'm not sure what you are looking at, but I would simply parallel the new horn with the old one. Then unplug the old one. You would be using the factory relay to make the horn work.

If you are replacing an existing horn, you might need some need some addition wire http://www.amazon.com/Dorman-85739-Orange-Gauge-Primary/dp/B002H9BHUE/ref=sr_1_1?s=automotive&ie=UTF8&qid=1397824755&sr=1-1&keywords=auto+wire and some crimps such as: http://www.amazon.com/Neiko-Solderless-Terminal-Connection-Stripper/dp/B000K7GRCI/ref=sr_1_2?ie=UTF8&qid=1397824730&sr=8-2&keywords=auto+crimp

yup that will work , the horns only care about how much PSI you run not voltage. I blast them at 200 psi some times . I have them on my bagged 2002 expedition I lovem

Unless you're crossing an ocean on your sailboat with a finite amount of power, selection goes as follows: if you have a relay already, just wire up. If you do not have a horn relay on your vehicle, like an old car or truck, wire in 1 relay for the horn set. I really respect this set of horns on my 190D 2.5 Turbo in San Francisco, anything larger would not represent an automobile. When a car has train horns, you can't visually match the sound to the vehicle trying to communicate. Only twice has this horn been unaffective, those two people were obviously under the influence and already decided what they were doing. So, only twice have I wished I had an air horn. Tonight being the 2nd time in a year of driving in SF, using them 3 times aday. These are great, and with an artful application of the horn, it can be made to sound different depending on your needs.

I have seen sockets for this relay however this seller doesn't include it. I have seen them around sold together if you don't see it here check on ebay. hope that helps!

Steve, I installed the Fiamm 72112 Freeway Blaster and the Fiamm 72102 12 V High Note horns (I really think that you need both) on my 1966 MGB that has a 20 Amp Fuse and a stated max Amp draw of 3 1/2 amps. I had planned on installing a relay, but horns worked so well that I never installed it. I would simply install one or both of these horns and if they blow a fuse, then install your relay. I hardly ever use my horn, but when I do they do get Semi drivers attention. Best $30+ dollars I ever spent. I hope this helps.

They just come with anything but mounting brackets but they only draw about 4 amps so you don,t need a relay just a switch.

Sure these can be wired as a direct replacement for the stock horns, or I suppose these could be wired along with the stock horns. These are louder but not train horn loud, so the "friendly toot" is still possible.

I comprtely bypassed the factory system. I installed horn button on dash,one wire to ground and the other on new horn relay. I also bought a new horn. Some installation was required for the new rely and horn, and worked well.

I only ordered the horn kit. I bought the switch at a hardware store because all the reviews for the buttons were really bad. I spent around $10 for the wires, connectors, and the button. But depending in where you want to mount it you will probably need to get more tubing, another $5 for 10 ft also at a hardware store.

Yes works!!!but I recommend you buy a wiring harness (Universal plag and play wiring harness SNPNP) for better performance of the horn.

If you only use one tone (Hi, or Low, not both horns, same circuit), no, you do not need to install a relay; just connect it using the original horn wires (polarity does not matter). If you are using both the High, and the Low tone horns, wired in parallel (best option), then I would recommend a relay, and direct connect to the battery (with an inline fuse) for maximum power transfer, and maximum loudness. I used two sets of both horns, on two separate motorcycles, in parallel. I also used a relay, controlled by the OEM horn circuit, with a direct connect to the batteries, for maximum volume. A relay is less than $10 at any automotive parts store (Wal-Mart likely has the lowest price). If you need help with electrical circuits, here is a great book's ISBN-10: 0760327165, "Motorcycle Electrical Systems: Troubleshooting and Repair (Motorbooks Workshop)". Check your local library for a copy, or purchase it here, on Amazon. Cheers!

Kevin, I simply swapped in this new horn and removed the (much quieter) OEM horn on my motorcycle; I did not change the fuse. Further, the draw of this Fiamm horn does not require a relay. So I've had the Fiamm installed for over a year and it works great after many honks.

I was able to find this information online. You may want to double-check with either your mechanic or your dealer.The horn fuse and the horn relay are in the left front under hood fuse/relay box.This is a location diagram and the inside of the box. Sorry about the size of the diagrams. They don't allow us much space here. The fuse and relay should be marked in the fuse box lid.Here is a wiring diagram just in case you need it.

I just hooked two Wolo's up to my stock wiring from the 87 van. and went to a bigger fuse because I'm running dual horns. They are loud and sound great. I didn't use the relays

Yes. If your old system had a relay, then you should use one with this otherwise you could burn the contacts on the switch. The switch provided in wiring kit is light duty and open. Depending on size and amperage-draw of your horn, you might want to look for something more durable.
