The video on Wolo's website says vehicle's existing horn wiring can be used. My wiring is undamaged, so do I need the wiring kit?

You don't need wiring kit, but it does require heavier duty wire and horn relay (included with Wolo horn) to handle requirements. Otherwise you limit the volume. Check size of factory wire.

No...Plug your "hot" wire on the posi and be sure to make a "neg" wire tail and ground the horn unit good. Giddy-Up, Beaver

I don't see why not, if it is undamaged. There is nothing in the new horn setup that precludes you from using standard "working" wiring from an old horn.

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.

To test whats not working properly, check polarity and connect straight to battery to test horn on its own, have heard of problems but have had none myself. Must run off of the relay provided and I made a direct connection to battery for the horn from the relay, the other side of the relay to the old horn wires. Did your old horn work?

Yes, but the wire was light gauge aluminum, and may not be enough depending on where you locate the horn. I went to hardware store and bought some 14 ga. stranded.

I installed the two horns by running power to each one and grounding to the chassis. I also used a horn relay kit, this one: Wolo (MCHWK-2) Air Horn Wiring Kit It was pretty easy to figure out. I installed this one a motorcycle, so I replaced the relay that came in the kit with a waterproof one.

I used the relay and did not cut any of the original wires when I installed these. I used the original horn harness to trigger the relay. The original connection on my car was a simple press fit spade connector, so it was easy. If your car has a fancier connector it might be more difficult to avoid cutting some original wires.

Yes you can hook it up to your existing horn.. instructions are simple to follow

Yes, if you use two horns you will need a relay. If you use one horn a relay is not necessary. It's a good idea to use an in line fuse if the circuit doesn't already have one.

I would get more wire (they don't supply enough) also different connectors. . (Butt, male and female connectors. .heat shrink style if possible) ...I didn't connect to my truck horn, I installed a separate switch..It's not too difficult. .Takes some time but is fairly simple. .The difficulty is mainly based on how you want your setup to be.

If you can, what you should be sure to use the kit is suitable the horn adptación in Your car

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

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!

if thats' the way you want to set it up that way. you don't need the original horn after you put the air horn on its' unessary over kill..

Yes it is plug and play. It will depend on where you want to mount the horn. If you need to use terminals and wire.I have a 97 Dodge Dakota the original horn was inside behind passenger headlight. I put this horn in front of the radiator. So Ihad to run wire and use terminals. But mine is still plug and play and I can revert to original position. I hope this helps. PS. It is easy

If it a car, yes just plug it where the two horn wires are and mount. Motorcyles must use the wire kit because there is no relay switch. Also dont get it wet.

Wiring hookup not hard, only problem I had was the tube that comes with horn is not strong enough for you to actually use the horn. It would pop constantly. Had to go buy a stronger air tube.

horns are universal. you should have no problem. as long as you follow the instructions and look up a relay diagram you'll be fine.
