What is the wiring diagram for a 2000 Buick Century 3.1 EGR connector?

I have a 2000 Buick Century with a 3.1 motor that has had the wires pulled out of the EGR connector. Im trying to wire it back up but not sure where my wires go. The wire colors are Gray, Gray/Black, Black, Brown, and what appears to be white. I need to know how the go into the connector from left to right. If someone has a 2000 GM with a 3.1 and cold look at the connector on their EGR valve that would be extremely helpful.

    Go to the dealer and ask them to print out the wiring chart for the EGR valve or buy a manual. The other thing you can do is find another car like yours on a car lot and open the hood on a test drive and make a diagram.

    "E" can be white or red. I wouldn't try and repair the connector, go to any good auto parts store and ask for an EGR valve pigtail.
