o2 connectors?

[ArcticSS]

Anybody know anyplace i can get o2 connectors? My front drivers side connector fell and burned right through on my headers. I just need the wire connector that connects from the engine to the open connector on the 02. Gm gave me a part # of 12191286 and told me they dont sell this part at all and look online. Ive been driving it the last 5 days and just noticed it today. But my check engine light did not come on. Would it hurt to drive on it since i just had it recently tuned?
