98 escort wiring

I have a 98 ford escort. I have a cd player installed in it. The heat and defrost controls are on the back panel. The wires to the defrost button came off. There are 4 metal prongs in a square, and 4 wires. Can someone help me, im not sure which goes where. The wires are green with a red stripe and pink at the end , a black wire with a blue end , a black wire with pink at the end and a green wire with a white stripewith pink at the end.
