The o2 Sensor is fully intact but the copper wire leading from the harness into the yellow side of the connector split yesterday when I was unplugging it.... I've unplugged the thing 50 times without a hitch before 
What to do? There's not enough room to get anything in there to remove the old wire and try to splice.
Here's the sensor itself...
and here's the connector. the wire leading into the yellow end broke off.
For a temporary fix I just shoved the wire in there and prayed it would stay on
My coolant temp guage was all over the place last night, completely unrelated right? First time for that too :/
