Some how I ripped the plugs off from my O2 sensor to the main wiring harness. So last night i tried hooking it back up by just wiring them together. There are four wires on the O2 sensor two black and a blue and white. Here is how i hooked it back up, it is running alot better but still a check engine light is on.

--------------Blue---red/white
02 side-----white---pink/green--------truck side
--------------black----black
--------------black----brown

Does it matter which black it hooked up to the other black and brown?? Any help would be great, thanks guys.
