If you have a new ACDelco pig tail there will be letters on the plug (don't know if aftermarket plugs would have the letters). A wire diagram should show what letters go to what color wire.
If I'm not mistaken,
(depending on which O2, the purple and tan wires could have a white stripe)
If there are no letters on the new plug then check the O2.
Also to be sure, the plug goes in one way, You should have at least one more O2 that you can check and see what wire goes where. They will all have basically the same color and plug into the O2 in the same way.
On the front O2 Sensor, the signal wire s Purple. On the rear O2 Sensor, the signal wire is Purple and White. (You will probably have to look at the wire colors on the main harness side of the O2 Sensor connector, not on the sensor itself.)
