Reason is, the power for the horn comes through the airbag circuit, the yellow-jacketed cabling with the flat connectors. When you install a Momo adapter you have to remove the clockspring, thus you lose the power wire going through the column.

The solution, thanks to Ray Kawski and Matt Ostlund, is to run the yellow/green wire from the spiral (clickspring) harness to the back of the wiper stalk assembly. That will provide power to the brass/copper contacts inside, to which the spring and the pin you create will touch.

I did this last night and it works as advertised...
