Steering Wheel Swap

[jpoole]

Hi guy, just picked up a 1969 Chevy C-10 and need to swap steering wheels as the 17 is too big for my gut. I got a 1993 Silverado wheel off eBay and put it on fine, however cannot figure out how to connect horn. The truck supposedly has a CPP tilt column, but I do not see how to connect the horn wire to the setup. Once I pull the wheel and expose the plastic pieces there is a brass button that controls the horn.

Anyone that has done this please help as to what kit or adapter setup I need to get. Been searching but cannot find what I am needing.

Thanks, Jeff
