Mountney Steer Wheel - how do you hook up the horn?

I installed a Mountney Steering wheel/hub last year. It looks great, but I never figured out how to hook up the horn. I know I have to remove the brass slip ring on the old steering wheel, but can't figure out how to get it connected/wired. For those that have done this, any ideas or suggestions?

Real simple

Pop the brass ring off the plastic backing. Solder a wire to it thats long enough to reach the horn button plus a bit extra. Reinstall in plastic ring and install to the base of the wheel. Install on the car and crimp or solder the wire to the eylet thats in the center of the horn button base.

Thanks Stewart.
