Here you go....... first up is the top of the wheel. The red arrows show the holes the screws go into, you'll see the screws later.

Next is with the horn switch in place. There are a couple of tabs on the bottom of the switch that engage holes in the top of the wheel hub, so you may need to wiggle things a bit to get it in position. You can see the screw holes in the bottom of the holes in the switch.

This is one of the three screws, shown with the insulator sleeve on it.

This shows the horn ring in place, the screws go through the ring and down through the switch into the wheel hub.

Should be all you need. This is from a scuzzy wheel on a recent acquisition I haven't really started on and the pics were taken as I disassembled things. Questions??
