Just an FYI, Murphs has a wiring harness that will allow you to keep the original horn in the loop and it makes installation a breeze. $20 well spent IMO.
Totally agreed. I bought that harness and it is nice. I love having BOTH horns, because it is yet more sound. Plus I can tap the horn button super-fast and get a "beep" out of the OEM without resorting to the full megablast.
One should *NOT* attempt to run the Stebel Nautilus horn through the factory switch/wiring. It requires far too much current, so the voltage will drop greatly, causing the horn to be weak, if it works at all. It will also wear out the factory horn switch. Always use a relay and connect directly (fused, of course) to the battery.
