Hello,
New to the forums and hoping somebody can help with this:

Bought the E-track expansion pack that includes two switches and added this pack to my sons Thomas and Friends standard pack, that has a standard blue/yellow controller and that can take two accessories.  

The expansion pack switches come with wires that have connectors on the end and the blue controller doesn't accept this type of connector.  Is it possible to connect the switches to the controller and if so, how?  Do I just cut of the connectors and put the 3 wires into the terminal of the blue controller?

Thanks
