Gloves?
Yea I was thinking about that too. 1QUICK4 is right, basically the postive connection could ride on a tab against the steering wheel touching another peice thats stationary on the console. Both peice would be seperate but have tension against each other to keep a connection.
You could disable the horn and use the existing wiring that way. The horn is likely the ground. So just reverse it and it should work.
