Ok,
I think I finally found out why the darn thing is giving me headaches:

thanks guys, just trying to be helpful.
Looks like the Momo aftermarket hub isn't the same as the Momo Porsche supplied hub. Look closely at the relative location of the brass contact surfaces in these:

The contact ring is further away from the steering shaft in the 2nd photo. The horn contact is designed to work with the 1st. Neat.

Ok, It works Now!!! Thanks Tosi and everyone else.
The trick is to get a cotter pin, trim it to size and insert it into the hole where the horn contact pin would fit. The head of the cotter pin will allow the contact edge to rest inside. This will offset the horn contact enough where the horn will work.
Again, if i knew the diameters of the contact surface were different from the RS and Momo, I would have been done a long time ago!

This is a great write up. I made a few resistor setups that had the correct resistor and plugs (0.062" male Molex). I have more resistors, but no spare connectors.
I also have a Motorsports Cup wheel like iron images pictured above, but have always been hesitant to install it. Put a 3 spoke airbag wheel in and have been happy with it.
