Horns - Plug & Play Replacements?

[Tomato]

Anyone know of replacement horns that will plug into the stock wire harness? Looks like they jump from 1 horn to the other, and each has a different plug...

Did you find any solution to this? Factory horn sounds weak.

Unfortunately, I have not.  Factory horn is a joke.  Sounds like a sick calf.

Yeah I've been hoping for a decent replacement plug and play horn for almost a year now.... forget about it until I use it.... shameful!

I just added 2 additional horns.  Relay tapped in to original horn wire.  Mounted new horns on firewall over engine.

Would be great if you could post some pics.

TOMATO:   here are pix of my horn additions, 2020 gmc double cab 2500 gas:

 

The silver bolt next to the yellow wire in 2nd picture is an existing bolt on a bracket extending towards the engine on the rear inboard corner of the battery.   Used a scrap 1"x1"x1/4" piece of aluminum angle and fastened the horn assembly to that one existing bolt.

 

These are just Auto zone/Adv auto horns off the rack (they come this color).  Nothing exotic but a very different tone (very loud beep) that makes the combination of the 4 horns more noticeable while not being a discord.     I looked on Ebay for those 4 horn sets that used to come on cadilacs but they were pricey.

 

I measured amps, looked at fuses, and decided I HAD to add a relay which just gets the hot right off the battery.   The relay delay is not noticeable.
