I've been on and off about a horn upgrade for years. Amazon is selling a Stebel Nautilus for about $40 right now. I've read Salzman's horn install a couple years back (the link no longer works). How well does the Nautilus fit into a 220?

I thought production stopped a while back, and I looked into a WOLO BadBoy horn, but they had mixed reviews. For people that have done this, what extra components are needed? I keep hearing about extra wires and components and stuff. Looking it up, these are sold on amazon too:

(good reviews: and comes with a 30amp relay!)

I'm tempted to buy a Nautilus + the nicer wiring kit and handing this off to my shop for them to install, at my next service. To anyone who has done this, especially on a 220, are those parts sufficient?

I vaguely recall from the blog link that the guy had to drill a hole or two: I'm wondering whether the longer cables (in this wiring kit) get around that by allowing them to be extended the long way. If so, it's just a matter of opening her up and replacing a few parts? I'm hoping labor is cheap if I do this at my next service, when he's already all propped open. I'm definitely not capable (mechanically) of doing it myself, in addition to the fact that I have no tools.

This dosen't sound bad. Can you post some pics?

Also, be aware that many of the Nautilus horns you see on eBay and Amazon are not genuine Stebel, but China knockoffs. You can tell because 1) they're much cheaper, 2) look slightly different.
I don't have any experience which either one, so I can't say whether or not the knockoffs are good or bad.
