O.k., here is the imitation.
It's after mid-night, and uncouth to test the horn now. I'll wait until my wife has an appointment outside the home.
In any case, this is one variation on the theme.
In my case, I have the SH847 R/R (recommended by
@DEcosse -- tastes great, less filling) with the mount designed and fabricated by
@Bedifferent. As mentioned above, his mount for the R/R, seems tailor made to provide room just so for the new horn's compressor - meeting the requirements of vertical placement and short air hose run. And all fits nicely under the left side cover (California evap controls long ago removed).
The wiring is a mess, but hey, what is hidden under the seat doesn't bother me.
In the photo below, you'll notice the relay base is there -- I'm waiting for daylight to see if there is any smoke when plugging in the relay.
In sadly typical fashion, this Chinese made item is lacking, with bad translation and nearly incomprehensible instructions. The supplied wiring is 18 ga at best, and the instructions call for 12 ga (12-24 V) and 10 ga (6 V).
I am hoping the load is significantly less than the supplied 30A fuse, as I suspect that fuse will not protect the wiring. It appears
@TXtriple recognized that, and used more stout wiring in his installation. I may be following suit out of necessity. We shall see.
As for the horn mount itself, I need to follow another practice of
@TXtriple and use chrome paint on the forward clamp.
In all, this installation took about two hours, with half of that just uncovering - remove windshield, remove seat, remove instrument cluster, remove bearclaw, remove left side cover, work, repeat in reverse order.

Thank you everyone !
