iJDMTOY 12V Horn Relay Wiring Harness Kit for Car/Truck Blast Tone Horns

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.

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.

K not sure what everyone else is smoking here, but i'm going to confirm as of 1/23/16: This fits 2010 Subaru WRX with no issues. (1 Relay) (4 Spade Connectors) +/- for to each horn 2 Bullet Connectors) + Trigger Wire & - Chassis Ground (Note some cars do not utilize bullet connectors. Cut off and crimp a male spade (for Subaru's) (2 Battery Connectors) +/- for Battery Terminals INSTALL TIP: NO SOUND so i plugged in negative (Bullet Connector) into my OEM horn Trigger Plug and voila it worked. I'm coming from a setup that had the subymod harness gen 1 paired with hellahorns. That harness was absolute junk and failed within a few months of use. I than had that company send me another (gen2) i believe. This also failed. I applied further weatherproofing around the connectors etc. but the relay seems to have failed after a few additional months. Fast forward 1 year and half with out hella horns! Upset at the lack of ability to honk at idiot drivers, i decided to wire jup my own harness, than i found this.This item fits 2010 Subaru WRX and would fit a 13' wrx and a 11 legacy. Everyone stating there are cables missing, or the length is too short?? Its beyond me. Lack of instructions is why its only getting 4 stars, just follow my notes above and you should be good.

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.

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)

Stay away from this item!!! It is not intended for hellahorn installs, it is a very generic relay used for multi-purpose wiring of other items. This item was completely confusing to use with a hellhorn install. It came with bullet connections, and there are no bullet connections used in the install. Also, there was not sufficient wiring, causing you to attempt to "stretch" the wires causing damage. After searching for online help with the connections, there was nothing to be found other than some simple "3rd grader" style pics that gave less than a sentence description. Came with no instructions as well. Overall, made to look good, but still made with cheap materials that broke on me. I ended up throwing it away and buying a SUBIMODS V2 plug and play harness!

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

Perfect pairing for a set of horns to go on an older carr

Bon produit , mais pas de plan pour le raccordement ...

Installation is easy

Perfect

Doesn't come with male connector. Only positive terminal connection. No suitable for vehicles with two wires from the switch

The wiring is a mess, we had to alter the kit to work as advertised
