simply connect the module to a 12V DC power supply and using the push button, follow the instructions & program the module to operate a 2,3 or 4 aspect signal. then connect your colour light signal and test that the module has been set successfully.
Then install the module on your layout near to your signal and watch as your trains trigger the signal through a realistic (adjustable) timer sequence.
