Here's a quicky review of the horn kit for the compact nautilus horn from Adventurer's Workshop. At just over $30, the kit ain't cheap, but for semi-instant gratification, I think it's worth it. At least for a "Fear of all things electrical" guy like me.Uses the existing horn button. Steps were- yank old horn,(one nut) thread on provided spacer, add provided bracket to horn, plug new wire into old horn lead and shrink-tube it to hold it in. Add pos/neg leads to horn.Bolt horn to spacer and wiggle it for a half hour, trying to find a place it won't foul the brake cable.Find a hole for the relay(Not THAT hole) and crimp and plug the leads from the horn and the leads going to the battery.Stop what you're doing and go to the auto supply for stinkin' in-line 15 amp fuse holder.Finish connections. Blow horn and annoy neighbors.Hey, it DOES sound like a train! Pros- It comes with everything you need (almost) Bracket, threaded spacer, color coded wires, crimp connectors and bolts/washers.Everything fits together and seems to be quality stuff. Cons-The instuctions left something to be desired-like a diagram! a napkin sketch! Anything! Sorry, I was raised on comic books, and a picture IS worth 1,000 words. A simple line drawing showing basic orientation of parts would have shaved an hour off install. There was a photocopy included of what I'm assuming were photos of the horn and relay positions, but they look more like inkblots. Also, for my $30, please include the 99 cent in-line fuse holder, OK? Just charge me $31. All said and done , an hour (or 2 for me:huh ) in the garage and you'll be honking at and scaring the piss out of friends and neigbors! Seriously, if I can do this , so can you.
