HDV6 control panel - which wires go where?

Help. I took the control panel of my Hoover HDV6 tumble dryer and the 4 wires that attach to the on/off and the heat setting button have pulled off before I could photo them
2 are green, 1 has two red wires going into and the final is a white wire. Do I attach the red and whites to the power and the green's to the heat setting?
Also, does it matter if the red wire goes onto the top or bottom of the connectors?
