Commander Fuel Rail Pressure?

I have the Commender with the fuel pressure kit but can't get a reading on the rail pressure. The lift pump pressure works fine. I checked all the wires twice. I turned the fuel pressure on in the Commander but get nothing. Is it me or is something not right? HELP PLEASE.

Did you hook the Green wire from the fuel pressure kit to the Middle wire of the rail pressure sensor?
