Diagrams
Hiya Sherpa, just had a look at the wiring diagrams for the american and english switches. It appears from the diags that the switch may be supplied with a prewired plug. That is assuming that they have now adopted the US loom for lighting.
If that is so you will just have to remove the jumper plug from yours and connect the switch plug. The top part of the picture shows the UK switch, the bottom the US jumper plug.
