Are you saying you just took an old connector (that would plug directly into the original wiring socket that the single horn is plugged into) and connected the wires from each of the new horns into the single salvaged connector? How many wires does a horn have and is it obvious what they’re for? L, N and some sort of on/off L? Or is that wishful thinking?

Re: How is your HORN sounding?
This is what I constructed using an old salvaged VW horn connector and a set of wires.
Its just a simple splitter cable with the correct plug to attach to the existing vehicle wiring loom and free wires to connect to the pair of new horns.
Dont need to touch any of the original loom, just unplug the single horn and plug this in !!

Each horn has only 2 connections, and is not polariity conscious.
No issues with any canbus problems either due to the increased current drawn by the extra horn as its not monitored anyway !
Heres a view of my horns through the fog light aperture - sorry not very detailed :-

Heres a typical VW horn assembly - I just chopped off the connector (the bit with the white dot on !) and soldered on 2 sets of wires to each to connect to the new Hella horns :-

Connector ready for soldering wires :-

Finished wiring was covered in epoxy resin and wrapped in heatshrink sleeving for waterproofing.
Hope this guide helps .

Re: How is your HORN sounding?
Great info and guide Tiger
That's a tight enough looking space to work in and I'd assume a two handed job, my hands are big
Is 1mm2 cable heavy enough for the job?

Re: How is your HORN sounding?
Access is a little tight through the foglight aperture - once you get the damn foglight assembly removed (thats another awkward job) , but you can also simply remove the complete underfloor tray beneath the engine as well to gain a little more access. The other option is to remove the complete front bumper assembly which is a right faff of a job.Deleted user 925 wrote: ↑Sat Jan 23, 2021 10:29 pmGreat info and guide Tiger

Uncoupling the existing horn from the plug in the wiring loom can be fiddly too. Its damn tight with limited access for 2 hands !
Its best done after you've unbloted the horn from its bracket, for which you'll need a short length 13mm spanner and plenty of muscle in that confined space!
A new 8mmx16mm long nut and bolt with washers is then required to attach the 2 new Hella horns to the existing horn bracket.
I've done this mod 5 times now for other owners. Its gotten a bit easier now !
For the salvage donor horn, any thing from the VW range, Golf, Polo, Passat, etc vehicles between 2010 onwards is fine. Also Seat, Skoda and Audi ones are suitable too. I picked all mine up from the local breakers yard for a couple quid, but that's probably best done during the summer months! Of course there's always plenty available on Ebay too.
Removing the required connector from the old donor horn is best done using something like a dremmel with a small cutting disk. Its easy then to remove all the excess plastic mouldings around the connector carefully. A junior hacksaw and a couple of hand files also works with care.
For the new twin horns, I always use new ones from Hella as they are nice and compact and fit in the available space perfectly. They're just as loud as original VW ones, and so much cheaper too.
1mm2 cable will be fine.
Let me know if you need any more help or info.

Re: How is your HORN sounding?
Sound advice!! from tiger tony, I decided to use his wiring adapter and the hella horns job took me a few hours. It’s a little tricky as mentioned because of the limited space, but there is enough room to fit both horns and get your spanner’s in to tighten up. A bright torch also helps to check everything is fitted correctly.
