I have had to replace the plasterboard on my bathroom ceiling due to a leak, but the details for where the wires connected, were written down but seem to be wrong.
I need to connect the wires from the light pull cord to the light fitting to the fan.

Please consider snapping a picture so we can see what the connections will be. Then use the "Go Advanced" tab to add the pics to this post.

One other question. The light and fan are controlled by a pull switch on the device, correct? There is no wall switch involved with this circuit, correct?
