Maf sensor help please

I replaced the sensor harness and thought I did all the wires right, but now I get a reduced power with no engine light and no flow reading for g/s. Can someone post a picture of the wire harness plug colors so I can compare or let me know the color order please? I have the "L" style 5 wire sensor.

Thanks, I'll give that a shot and see what happens. The book I have on it isn't even close to that.
