Ok, now the single "high note" horn also stopped working -- it has some oily looking sludge coming out of it's seams (also noticed I blew the 15A horn fuse again, so I picked up a 5 pack at Pep Boys). Got myself a deal on a pair (one high tone, one low tone) 12V Bosch horns on e-Bay, they look new, never mounted. tested them individually and they work and the Jeep + plug slides right onto the new horns' electrical tabs. Now the problems:

The new horns look very similar BUT they have a positive AND a negative tab. No biggie, I figure I'll just ground the other side! It seems that no matter how I mount them or which tab I use as the negative or positive side as soon as I ground them they are honking -- even when I am NOT pressing the horn button on the steering wheel. The 15A fuse is holding up fine. What next???
