The horn transplant is done.
When they say "easy", that's a relative term.
The main issue is space, or lack thereof. You can certainly pull the top of the grille back and up a long way to get the old horn out and the new horns in, but you will scrape your hands a bit!
It's a really, really tight fit. I had to loosen the horns on the bracket and turn them a bit, so the trumpets were pointing straight down when installed. There is a plastic bulge below there that the horns hit if they are at angle. I think it would even be possible to have the horn mounting holes a little higher up on the bracket to give a little more clearance.
The wiring harness is great. Well worth it. They give you a new mounting bolt, but I re-used the original since the Torx head is fairly easy to get to through the grill. I think they give you a new one in case you drop the original and lose it!
It's a bit of a pain, but it is done. The results? The horn sounds great! 400Hz and 500Hz Hellas give a nice sporty sound. My trick with baby powder to outline the original position of the 4 screws you have to remove worked like a charm and reassured me that everything was back in place correctly.
I would have taken pictures but honestly there is no room, so I was just glad to get them finally bolted up. I took it out for a quick spin to make sure the adaptive cruise was happy (it was), and bizarrely saw not one, but two Taoses in a 15 minute drive near my house! One black, one white!
Here's the clown horn. It even looks pathetic...
