HELP! Cut Wire on Sensor Plug

I had a code of P0154, so i replace the passenger side O2 sensor... in the process i found that a wire had been cut on some sensor plug (never cut by me) anyways its the green one in the pic as you can see... the plug has 4 wires, a black, purple, blue and the green one that had been cut... I'm assuming this is a ground wire? what does it run to? what should i go about treating it? the corvetteforum guys haven't figured it out yet... so i'm posting over here...

The green wire is a data/voltage line. GM is very good at keeping all grounds black. Since it looks like it was cut close to the weather pack connector, you are going to need a new pig tail connector. They are not exprensive. Try Speartech, a sponcer over on the right side. You will have to cut and splice in the new pig tail into the wiring harness. Just make sure to use some heat shrink tubing on all the wires where they are spliced together.

Its definately a wire coming from your FRONT o2 sensor harness . Since I dont have the schematics in from of me I cant tell you which wire that represents. But do a search for the wiring. It should be fairly easy to find.

Nice! i will save that to my favorites too!

You can also go to the Gm dealer and get the pigtails also. Although you will more than likely have to order them but usually will have them the next day.
