Today I realized that my o2 sensor plug was hanging beneath the car. What i need to know is where it plugs into. (The actual sensor is screwed into the exhaust, I just need to know where the plug plugs into) The car is a 94 ls 4 door with b18c5 swap. Thanks for any help.

 

anybody? car is running like crap with it not plugged in.. dont wanna wait til monday to call the dealer

 

It's kinda hard to explain, lemme see if I can get a pic of it.

Thanks for the helpful pics.. I have located the plug but they do not match up because the motor is a 2000 b18c5 and my car is 94 ls. What shoudl i do in order to solve this problem?

 

Thats because your '94 is OBD1, and the motor is OBD2. I'm not sure of the wiring, you might be able to get a connector at a junk yard and wire it up, but I'm not sure of the specifics. Good luck.
