Really great for the price.
I was thinking on making my own wire harness for my hella horns on my subaru. Then I seen this harness for $12.00 and I was like ill take a chance on it worse case I wasted $12.00. When I got it I was very surprised on how much wire is in the harness. It worked great for wiring my hella horns in. I couldn't of made this harness for no $12.00 well worth the money.

2011 Mazda MX-5
I replaced the Nautilus horn with this Hella Supertones and WOW! so much better. The wiring harness makes the install so much easier. Here are some tips to for a Mazda MX-5 Miata install with this combo:1. There are mounting holes already in the car (Thank you Mazda!) you just need bolts. So pickup a pair of M6 - 1.00 x 16, and two M6 lock washers. You can also use M6 1.00 x 20 bolts. BTW, I also used some thread locker to keep it in there.2. Take off the front bumper. Yes, it makes it so much easier.3. The stock horn connector is a spade type and the kit is cylindrical, so you'll need to figure that out by changing one of them. I just change mine to new spade type connectors.4. Run all the cable as per the directions in the kit and zip tie it to keep it nice and tidy.I hope this helps, LOVE my horn now.Dumb drivers and pedestrians on their phones too busy to watch where they are going to do not like how loud my horn is...LOL.Oh, some have use the stock horn connection, but I figured, since I'm already in there, why not do it right the FIRST time and not have to go back in and fix it.Here's the link to the Horn I installed:HELLA 003399801 Supertone 12V High Tone/Low Tone Twin Horn Kit

Nice harness, weak relay
My intention was to install this on a 2018 Civic with Hella Supertones, since the friendly "meep meep" stock horn was somewhat embarrassing. I was initially apprehensive of the cable lengths, but after installing the horns and harness, it turns out my concerns were unfounded.There are two potential points of improvement here. First, the end that connects to the vehicle's wiring has what look like female banana clip connectors. I've never seen those outside of home stereo applications, so I cut them right off and soldered it into the system using the College Hills horn adapter.The second thing, as the headline suggests, is the relay. Something is definitely wrong with the relay that comes with this harness: honking the horn with the in-box relay results in one Supertone horn beeping slightly but noticeably before the other, and the beep doesn't sound as strong as I'd expect. Replacing it with its Bosch equivalent fixes that right up.So, if you're buying this harness, save yourself the trouble and buy the Bosch relay with it (or just use the one that comes with your Hella horns, if you got that option), and get rid of the one that comes in this product's box.Both of these are somewhat minor inconveniences so only one star comes off. Other than those things, this harness looks and feels very well put-together, and does exactly what it says.

Nice relay harness.
Nicely put together relay and wiring kit for a two-horn setup being added to your vehicle. My installation was to replace a single horn setup for a 2015 Honda Civic. The only way you can figure out what wires go where is to look at the photo on the Amazon website ad which shows the two horn connectors, the battery + and -, and the feed back to the original car + and - connections from the factory (hint, it's the bullet shaped ones). I had to cut off the bullet-shaped connectors for the original Honda connections and solder them together, not a big issue. One issue is that the feeds that go to the battery (+ and - ) should be foot or so longer. I had to splice in an extension, and the Civic is not a wide car. Each installation will be different, so I expected to have to do some home wiring. The fee a new pair of Hella 007424801 Twin Trumpet High/Low Tone horns. The original meep-meep POS Honda single horn only pulled 3.5 Amps. The new Hella units pull about 6 Amps each, thus the need for the dedicated power feed and relay. Works great.

Good Harness, but not for every appication
I have a 2021 and 2025 Subaru Forester and you will have to make cable adjustments. extend and move the cables since it;s not a perfect fit and the battery is far back. I recommend understanding the cables and relay; to understand the cable configuration needed before starting to work. Overall for the amount of cable, it's a good deal since it serves as a base to start the job, but certainly not a plug-and-play application.I wish the harned brought a piece of paper with some basic cable diagrams and instructions to avoid all the confusion, since in the case of a Subaru there is an extra cable left once you install everything else. (there is an extra ground for the relay itself that needs to be bolted somewhere)

The main relay broke after 12 hours
The harness went together super easy took maybe 5 min to set it up but my issue came the following day when I was cut off in traffic and the horns would not work because the relay got wet from the rain the night before now I have to go out and buy a new relay for like 10 dollars which isn't much but overall it's made well as far as the wires go but you might as well just pre plan if you buy this buy a good relay from a parts store that comes with a minimum 30 day warranty

Universal my patooty
It was supposed to fit my jeep wiring wise. The directions are for the birds not supposed to have to cut wires but none of theres work on any of my jeeps even when it said this will fit your vehicle. No where xlose and the instructions are terrible and no mention of extra wires tbat need to be left only cause i dont see wby theres 3 sets of 2 wires one out neg. side? and one out pos side and one out middle also a neg connection and pos. connection . Its supposed to hook to existinv horn which is alreaxy got power. Needless to say it didnt work and cant recund im sure cause i modified its newness by crimping wires. DO NOT WASTE YOUR MONEY
