Thanks for the video. I have a pair of Sharp Tones that I put on my Honda NC700X motorcycle and all I needed was the screen shot of the diagram that you circled. Piece of cake. Note to motorcycle riders if you buy the Sharp Tone or Super Tones, you MUST install the relay! If you don't it may screw up your instrument panel--like it did mine. (wasn't permanent, but every time I hit the horn it threw a warning light & reset my gear counter) You'll need a 30A fuse-link (from your local auto store) and some 12ga wire w/connectors for that grade of wire (I used a large loop to connect to the battery post & a sleeve connector to connect the 12ga wire). Connect one end of the fuse link to the (+) on your battery and connect a 12ga wire to the other wire from the fuse; the new wire runs down to your relay switch pin 30. Just note to install the fuse link in the correct orientation--make sure the end cap--that opens to install the fuse--is on the opposite end of the battery connection wire. Meaning the end cap isn't the wire that's connected to the (+) post. You need to be able to install the fuse without having to undo the terminal (again). (major pain--especially if it's tough getting to the terminal connections inside the battery compartment) All the wiring between the horns and relay can be the smaller gauge wire (16-18)...then it's easy; all you need to do is run a pigtail connector off one of the horn's (+) to the other horn's (+), run another wire from the pigtail connector back to pin 87 on the relay. (note you'll also need two wires from the (negative) on the horns to fasten to a point on the frame to make a ground) I suggest connecting the pigtail closest to the relay to make it an easier hook up (shorter run). Then, connect the factory switch (which has a (+) lead and a (-) lead) directly to pins 85 (negative (ground)) and 86 (+). Done.
Thanks for putting this together Dan. I used it to install Hella Smart Tones in my 2012 FJ. It saved me more than a few hours. Still took a 1/2 day since I'm meticulous about keeping the wiring clean and as protected as possible from weather. For anyone reading this, the only issue I had was with grounds. Paint needed to be scraped off the "internal" body to get a good ground for the horns and grounding the relay.
I installed the HELLA Chrome 12V Trumpet Horns on my FJ the same way you did and wired the same way with the relay but I got no sound. After some research found you have to ground the horn with the second tab on the horns and not through the mounting flange. Boy are these things loud!! Thanks for your video, I could not have done it without it!!
The BEST install video for these. If you have been searching on how to install these, this is it. Finally. Also, this has instructions for relay, which many don't.
@@dingopatmo www.triumphrat.net/memberalbums/data/1217/horn-relay.jpg These devices take more current than your OEM horn ... the original wires are not intended for so much current. The relay provides a way to use heavier wire (more voltage gets to the horn) SAFELY, and the diagram linked above lets you control it from the old wiring and the steering wheel horn button -- without setting your car on fire !
Pete, the relay is designed to act as a switch for the horn. Your existing positive leads may not provide enough wattage to the run the horns at full power if there is no relay. When you press the horn on your steering wheel, a relatively small current is sent to the relay. The relay in turn will then provide a stronger current to the horns themselves.
Nice video Dan, Just to let you and everyone know there's an easier way do this. On the 2007 FJC the wiring for the secondary horn is already installed from the factory ready to use without any need for modification of the wiring using the oem relay. The wire with the oem connector is located on the right inner fender wheel by the hood rod. It's hidden on the harness with just a piece of black electrical tape. I myself bought the Toyota secondary horn and paid way too much for it...$49!
Dan thank you for your forethought and detailed documentation of how to properly wire these horns on my 2014 FJ TTUE. You've been a blessing, again thank you, US Navy retired.
Thanks for the instructional video. The ONLY video that was clear, easy to understand and used the relay in the process. It could not get any more on point than this video. Made my wiring installation a breeze!
You've got all of the steps correct. Here's a rundown of the leads and relay numbers: #85 on relay to Ground (use screw used to mount relay) #30 on relay to fuse holder to battery #87 on relay to positive connection on horns (top connector when bracket is pointed up) #86 on relay to existing horn positive connection (detached from old horn)
I have seen a lot of tutorials, MANY REALLY BAD, SOME GOOD BUT YOURS IS SPOT ON! GOOD VIDEO, KNOWLEDGE AND SPEAKING WITH SIMPLE UNDERSTANDABLE INSTRUCTIONS! THANKSSSSS!!!!
Thanks a ton Dan. Im a great carpenter but a mechanical moron. My horns went out on my 2005 Taco. I watched this video at least 10 times and bought precisely what you did except i used red wiring for the positive. I took my time and low and behold, it worked!! I actually learned a thing or two doing it myself...than paying the 4 wheel drive store as well.
Hi Dan, thank you for making this excellent video. Great information, list all tools req.,logical steps, good caution info so you don't get fried or ruin your FJ. Great editing job to keep it tight with just the right amount of info. The only suggestion I have is to use heat shrink wrap pieces instead of black electical tape to make it stay water proof longer.
Dan, I noticed that your placement of the Relay ground was between the painted sheet metal and the back of the plastic mounting tab of the relay. I think that may have been an issue with the left horn not working at first. The lead should be in contact with the screw I believe. Your demonstration video was what I have been looking for, for several months. Great job! Thanks
Thanks a lot for your video i´m Juan From Cali - Colombia and i have a Renault (Dacia) Logan and your video was very helpful and clear to let me install the Supertones. Thanks Again!
Hi Mr Dan thanks for this informative video. 1 question, isn’t it that there is a STOCK RELAY for the horn what did you do with it aside from installing a new one? THANK YOU
Dan - Thanks for putting the video together! Question,where did the second OEM positive horn wire attache to? I understand there was one that goes to the relay? First time doing this so just want to make sure i'm 100% before doing it. I have a Camry 2005, and I do a lot of city and freeway driving for work. Thanks for the help.
Sir have you seen/heard of ADDING a relay to a car’s headlight makes it brighter than the stock one using the same stock bulbs. It makes it glow more? If you do and have time can you please explain how. THANK SO MUCH
Great video, it took me a while but I finally found a video that helped and explained everything in plain english. My car also had only 1 horn, good luck finding something to fit my needs.
This is awesome , but why can't I just install them using the original wires for the OEM horns ? Like just add the relay , already have a horn fuse in the fuse box , no ? 🤔
My 83 Toyota 4x4 has1 stock horn with 2 wires (one is hot the other is not hot). I installed the horns using the Griots Garage instructions for 1 horn w/2 wires and it says relay is not needed and the horns did not work, but works with just 1 of the horns and using only the 2 stock wires. I have not found a video using both hella horns using the 2 stock wires with or without the relay.I do not want to make any mistakes. Thanks Ed
Thanks for this DIY horn upgrade installation video, just one question. My relay has a 5 pin, (extra 87a) I was wondering if could use that instead of splitting the lead wire feeding the (pair) horn's positive??? Sorry, I'm no electrician
Awesome instructions Dan! Couple of questions though: 1- connecting the wire that powered the old horn to the 86 coil of the relay is not too much current? As I understand it that wire was not the small current switch wire from the horn, to but the one that actually powered the old horns. 2 - how did you test the old horns wiring push polarity? It pushed positive, but how did you test? I'm working on a German car and my luck polarity will be bacwards.
What type of splitter did you use to create two horn leads? Are there other ways of doing this, such as attaching a ring terminal to the end of one wire, and attaching the two leads to the ring terminal?
incredible video. OKAY. to get this straight and confirm. 1.) use existing horn lead and run to relay. 2.) run a lead from battery with in-line fuse to relay. 3.) run a lead from relay into a t-tap to each one of the horns power. 4.) ground the relay and horns to each other. i.e. horn grounds to the horn mounting bracket and relay ground mounts to relay screw post? can you list the leads and corresponding relay numbers?
Hi, I have two questions. Do you know if on all Toyota car it's always a positive line first? and For the original connector for the horn, I have the same on my car... did you saw if it possible to use it again or it's just a connector single use? thanks for answers
Hi Dan, thanks a lot for the video. I installed my dualtone horns today, everything works perfectly except for the alarm... Did it also happen to you? Do you have any idea what could have gone wrong? P.S. The setup I chose is the same as the one on your video. Cheers.
i have that the mechanic connect but every time i set it an the one i like as soon as i turn off my ignition an take out my key and reentering i have to set it all over how must i connect the relay
Note : The horns are not labeled with a positive or negative terminal. it will not matter which ter- minal has a positive or negative wire installed to it as long as each horns has a designated 12 Volt wire and ground wire installed to it .
No need to put all of the spaghetti wiring into the system. More wire equals greater chance for short circuits. Keeps the wires short and the stock relay is sufficient.
Not impressed by the sound . No need for all this wires should use the stock wires and it will be more effective The car already has a relay and a fuse So all this work for no reason
I don't understand why people like these hella horns. This is definitely a downgrade , not an upgrade . They sound so wimpy. The original stock horns sounded 100% better. It's a grown up horn. The Hella sounds like a little go-kart.
7 years on and still helping people! Thanks for the clear and concise tutorial Dan 😊
I have watched like 10 videos on how to install these and yours is by far the best one.

This is a perfect install video. Clear, detailed, clean install that takes advantage of the relays, unlike all the other videos out there. Great job.
Thanks!
Clean install ? you're joking right ?
jshaw6600 and why do you have to use the relay? Cant u just use the old connection or what is the benefit?

The FJ stock Horn is already on a 30amp relay

Kinda sounds even wimpier than the OEM one. Thanks for doing the install and showing us how it sounds so we can avoid it 👍

LOOK NO FURTHER FOLKS. BEST INSTRUCTIONAL VID IVE SEEN IN A WHILE. ITS LIKE I WAS THERE LOL
dan thank you for your video, without it i could not figure out why my car horn won't work.

My oem horn lead has two wires instead of just one. Should I use both? Or just the colored one ( there is a black and a blue wire)
Thank you very much sir...
your video this one very helped for me....
Very good and educate....
Hi Dan, thanks a lot for the video. I installed my dualtone horns today, everything works perfectly except for the alarm...
Did it also happen to you? Do you have any idea what could have gone wrong?
P.S. The setup I chose is the same as the one on your video.
Cheers.
i have that the mechanic connect but every time i set it an the one i like as soon as i turn off my ignition an take out my key and reentering i have to set it all over how must i connect the relay
Is there a reason why the Relay is needed. Can one not just use the stock circut?
Excellent video many thanks
Note : The horns are not labeled with a positive or negative terminal. it will not matter which ter- minal has a positive or negative wire installed to it as long as each horns has a designated 12 Volt wire and ground wire installed to it .
Hey Pete, did the FJ not already have a factory relay inline?
What bolt did you use to put on the horn on the passenger side?
GOOD WORK
No need to put all of the spaghetti wiring into the system. More wire equals greater chance for short circuits. Keeps the wires short and the stock relay is sufficient.
thank u sir
Basically buy the wiring harness because shit never goes as smooth as it seems
1st green wire run i understood then you through in the 2nd green wire run with out explanation Confused the fuck out of me
Not impressed by the sound .
No need for all this wires should use the stock wires and it will be more effective
The car already has a relay and a fuse
So all this work for no reason
I agree. What a strange thinking this guy is doing.
I don't understand why people like these hella horns. This is definitely a downgrade , not an upgrade . They sound so wimpy. The original stock horns sounded 100% better. It's a grown up horn. The Hella sounds like a little go-kart.
wtf Dan not the best install directions
Thanks for the feedback. Suggestions on how I can improve the video / install directions?
