Here is my thread.... there are a few out there.
There are several older threads about adding a second horn to supplement the stock horn. (since Toyota was nice enough to give us a extra horn plug.)I've used the search function and was surprised at the lack of horn replacements. Anyone replaced their horn with something a little louder than the stock one? Any input appreciated, thanks!
This is also what I did, and the horn is plenty loud...There are several older threads about adding a second horn to supplement the stock horn. (since Toyota was nice enough to give us a extra horn plug.)
I bought mine from a vendor on the forum (part# in sig) and plugged it right in. Both horns together will make you jump if you're nearby.
THAT'S WHAT IM TALKING ABOUT!!!! RIDICULOUS AND TOTALLY NECESSARY!MY answer:
There's actually quite a few horn threads, sorry you had trouble finding them. I added the second Toyota (low pitched) horn and now it sounds like it should.
I used these same horns. The Hella Supertone is a great horn. Very loud so you can compete against cell phones and stereos. Very good horn and very easy to install like this.Another option is the Hella SuperTone Horn Kit, 118 db: from Amazon - Automotive $56.74
Use the OEM front horn wire, just splice it for the two horns, then make ground cables and attached them to the frame.
Does the Stebel horn mount the same way as the factory horn?I just replaced mine with a Stebel Nautalus compact electropneumatic and I am very pleased with.
Mounted is same location as stock horn by modifying stock mount.
