I been having a bit of bad luck lately and to make it worse, yesterday morning on my way to work I hit a huge dead beaver in the middle of the road. Tore the under plastic off that directs the air to the radiator, ripped my o2 sensor out of my cat, and have blood and guts stuck up under my car.

You may be thinking how the hell did the o2 sensor come out, I gutted my cat a while back (was bad and broken up) and was lucky enough to have done the spark plug non fouler trick to keep my check engine off. So with the nonfoulers on the o2 sensor it puts it a few inches further from the cat making it easier to be hit by road debrie. When I hit the beaver it broke the nonfoulers apart, one stayed in the car and the other on the o2 sensor. Luckily it the plugs just came apart and didn't rip my wiring on the car. However the plug on the o2 sensor itself did break. I need to drive my car for a few days till payday so im going to try to wire the o2 back up but the wires on the o2 sensor are different colors then the cars wiring harness connection. I found multiple charts and came to this,

(Car plug colors)
Y-signal +
BR-signal -
WR-heater +
R-heater -

(O2 sensor colors)
Blue
White
Black
Black

I believe they go like,

Y-signal + =blue
BR-signal - =white
WR-heater + =black
R-heater - =black

Im not sure how to tell the two blacks apart for +/-

Can anyone confirm that these wiring colors are matched right? Is this o2 sensor even needed since all it does is check the car and I dont have one. I know you need the first one for air/fuel ratio measurements but I've read multiple posts where people say the second one is needed and not needed.

Going by the wiring diagram, you have it right - the WR 'heater' wire will have +12v when the car is turned on, the other black won't.
If you don't have a diagram I can email.
