DIY: Custom Dual Horn Install Cable (NO SPLICE!) - Toyota Nation Forum : Toyota Car and Truck Forums

***FlawedLegacy*** · 12-15-2011, 10:50 AM

So a lot of people have asked how I installed my horns without splicing at all.

Dare I say, one of the easiest mods and SUPER SIMPLE to make this custom cable!
*Sorry for crap night time pics with my droid. Only light is small, junk LED flashlight

Tools Needed:
Wire Cutter
Wire Crimper/Needle Nose/etc
2 Quick Connect Female Ends
1 Quick Connect Male End
about 2' of wire

1. Disconnect the horn cable to the horn and you will see a female quick connect end on the cable (male on the horn).

2. Cut your ~2' of wire into 2 1' pieces.

3. Take your male ended quick connect and crimp on the two 1' cables (Make a "Y" cable)

4. (*OPTIONAL*) To clean it up, do a dry "install" and cut off any access cable needed to reach each horn. (Mine has about 8" to passenger side horn and 3" to driver side horn)

5. Crimp on a female end on the end of each cable

6. Connect cable male end to stock cable and tape it up to make sure no moisture gets in.

7. Connect cable female ends to the horns

8. Enjoy your new, fully removable custom dual horn setup!

*PLMK if I need to further explain something!!!!*

Awesome

You didn't want Hella Horns?

***FlawedLegacy*** · 12-15-2011, 11:02 AM

after hearing msncorolla's horns I knew I wanted those, plus they were cheaper.

Ahhh ok, I might as well post the vid here as it's on topic for horns, and it will help people decide between the two

Those Fiamms sound awesome. Which ones are they?

FIAMM Freeway Blasters. I got mine on Amazon for $18 for the pair

Did you go with the hi or low tones or both? And did you leave the stocks hooked up? And did you need a relay installed? Sorry for all the questions. Definitely want to do this mod.

***FlawedLegacy*** · 12-15-2011, 01:03 PM

one of each, removed the stock (one horn is where stock was), plug n play

Thankyou.

of course!!

ainako · 12-15-2011, 04:22 PM

so to get the sound similar to the video you need both the high and low tones? These sound much better than stock! The stock horn sound so emasculating...

LeanBurn · 12-15-2011, 04:27 PM

The last horn to me is the equivalent of nails on a chalk board...if you can remember those..

How do the Hella's sound in comparison to the Fiamm's in person? In the video, the Fiamm's sounds way louder. I also did this mod thanks to MSN's inspiration and help. The model numbers are 72112 and 72102. I love their sound together. Like a stock Lexus horn. Bought them for only $10 each, and I had a Groupon, so only spent $10 total. You must run the power to these horns in parallel (as Flawed has done) if you plan on using the stock harness. I tried them in series, but there's not enough power this way. Also Flawed, are you grounding on the radiator? Is that safe? I just ran the wire to a ring terminal I screwed on behind the bolt holding the horn.

The reason I got them is b/c of them being "Lexus-ish"!

No, the ground it to the back of the horn, there is nothing going to the radiator, just a crap pic most likely.
