GREAT set of photos, and a clean upgrade of the
Meep sounding horn.

A month ago It was early morning I was waiting for a railway train to cross a state Hwy. Several semi trucks were heading back to the rock quarry they were using their train horns to honk at the train. Taking advantage of the " It was not me defense of violation of city posted ordinance "

 

Thank you for posting this. I installed some Hella Sharptone horns today and it was very easy compared to my 2014 Prius.

 

Does someone have the part number for the absurd plastic push-pins holding the radiator cowl in place? A couple of mine are broken and I want to have replacements in hand when I do the horns.

 

check if this is the part you want the clips for .... part # 51420-47030
if that is the one the clips are # 90467-07220


Prime Engine Undercover Panel parts list

 

I found "90467-06133-C0" in another thread here and ordered some off eBay, we'll see. There may be different part numbers for the same item depending on which model its used in.

 

BTW, these Hella horns with the Toyota connector are an exact fit. They come in LH and RH configurations and if you orient them correctly the existing connectors line up perfectly. They ground through the bracket so there's no messing with a ground wire.

FWIW, the 90467-06133-C0 push pins are too small for the cowl. Trying 90467-07217 next

 

Following up, the 90467-07217 push pins appear to be an exact replacement, or at least close enough.

 

These are on sale for $20 on Amazon, got a pair for my car.

 

I put these Hella horns in and it really wasn't that much louder than the stock horn What is the purpose of the relay ? I just plug the harness on one side and the other pin I hooked to ground. I then honked my Highlander horn that was alot louder then this. Wth? So I'm boxing these and sending them back.

I might try these out. Otherwise I will just get the OEM Highlander horns.




Here are part numbers for the Highlander horns:
865100E040 and 865200E020

 

For those wondering #4 on the pic is the one that makes the hybrid sound in the Hybrids



SPEAKER ASSEMBLY, VEHICLE APPROACHING

Part Number: 8657048031

 

Well I tried these Hella horns and didn't like the sound ..looks I might use the freeway blaster that I used on my Gen 3 or put in the Highlander horn.

 

Hi. I’m trying to replace my horn on a 2021 prime. Can anyone tell me where to buy a pigtail connector to fit the one that the original horn used? I know that i can snip the wires and reconnect.

 

What happened to the original connector?

 

The male side is built into the plastic housing of the oem horn.
