Hello All, I have purchased a new steering wheel and horn buttom (wire attached). It looks like a newer style wheel but fits onto the spline properly. The horn button wire appears that it would go straight down the tube. I can not find any exit hole/slot on the steering tube. Can anyone tell me how this is installed down the steering tube and where the wire comes out to hook up? Does the wire go down the center inter tube or the outer thinner tube? Any help is appreciated. Thanks!
