I'd planned on pulling the tank but realized I could unbolt the tank from both bolts and hold it up with a bungee cord from the rear mount to the mirror to get to everything. That saved cutting the crossover hose and getting gas everywhere so that was nice. But, I'd prepared for that and bought a brass sharkbite hose splice from Home Depot - I'd planned on pinching the line on both sides with needle nose vice grips, cutting the line and taking the tank off, then, install the splice and two new hose clamps so that I could take the tank on and off in the future without draining it. The vice grips do a great job pinching off the line and with the splice I could lose only a tiny bit of gas when removing the tank in the future.

I purchased a regular softail top motor mount from eBay which has the horn mount. The factory horn mount fits the Steibel air horn perfectly - the Steibel is made to grab the factory nut and as you rotate the air horn it tightens up nicely to the rubber bushing. I ran my Road King like this for many miles.

On the Springer you can remove the factory horn power wire (I left the factory horn in place of course for looks) and run it back to the softail horn location (feeding it back through the fork) with no problems...I did cut the end off the wire and re-attached it to save from having to remove my windshield mount as the terminal wouldn't fit through the windshield mount. The Steibel air horn uses the factory hot terminal and I made a ground wire to the motor mount.

While I was at it, I tapped the fender light wire (orange w/ white stripe) and fed the passing light power switch from this wire. Now my passing lights work on high beam. The fender light circuit has a plug on the left side at the front of the tank and that's where I tapped it, the factory passing lights get their feed from a yellow wire from the headlight right there so it was easy to unhook the factory yellow power wire from the low beam and run a new wire to the orange and white fender light wire (which is fed from the Aux circuit so now my passing lights work on the Accessory position on the ignition switch too if I want.

If anyone has any questions please ask.

Here is a pic...more chrome!

As I mentioned, it's a much more attention-getting sound (seems louder), but measured about the same with a decibel meter.

These things are loud - I think most sources list them at around 118dB...
