Intermatic Pool Timer Wiring

[sjeffers01]

I have a three wire electrical plug setup and need to connect it to the timer. The instructions are on the door panel but I don't understand them. I want to know what color wire or terminal I am supposed to connect it to. The pump wiring was already done but one of the blue wires from the pump was loose. I was told I needed a three wire cord and plug. I brought in my pump manual and the assistant at Home Depot new about the Intermatic Timer and helped me buy what I needed. I couldn't find instructions that I can understand on connecting the power cord to the timer. I have attached a picture of the timer box that shows how I connected the power cord wires and the blue one that was loose. I am hoping that someone can tell me if it is wired correctly and if not, point out what I need to correct.
