Like Don said, the wire (which should have been part of the horn button kit) goes from the bottom of the horn button, to a plastic ferrule on the center of the column with a small ball point pen size spring under it. If it's missing, a call to Ididit should get you a replacement.

I don't want to sound like a smarta$$, but why are you using a Grant steering wheel on a Cobra? Did you look at or consider the LeCarras? If you looked at a LeCarra and Grant side by side, I think you would be (substantially) happier with the LeCarra. Not only will it look and feel better, but little touches like this will say a lot about the TLC you put into your build. LeCarras are about $50 - $60 more than the Grants. Column adapters are about the same $.
