I know they switched to the four prong dryer cord for better safety while running the appliance. Therefore, I didn't want to switch the cord so I went out and bought a new 4 prong receptical and I want to change it out. Smart I thought... But alas, I didn't think it all the way through to realize there would only be 3 wires behind the receptical. Can I wire this thing up in the wall correctly or should I return the receptical for a 3 prong cord and figure out how to hook it in to my 4 prong dryer?

Thanks in advance for the help.

Unless the existing wiring is in conduit (unlike except in the Chicago area) or wired with BX or you want to run a new cable from the panel then keep the existing 3 wire receptacle.

And convert the dryer over to use a 3 wire cordset.

The "conversion" is easy. It is most likely printed on a label on the back.

You will have 4 terminals or connections. Hot, neutral and Hot. And a case ground connection. The ground might be one of the terminals on the terminal strip or it might be a separate terminal/screw on the case. Most likely the terminals are marked with a lable or stamped into the case with (L1, L2 the hote, N - neutra, and G or a ground symbol for the ground http://en.wikipedia.org/wiki/Ground_(electricity)).

Either a strap or wire will go between the ground and neutral. The new cordset will connect to L1, L2 (black and/or red) and N (white).

While a 4 wire system is "better" it is only better if done CORRECTLY with a separate equipment grounding conductor (or equivalent such as metalic conduit).
