O2 Sensor Wiring

[m3f_96M3Power_4547fc3d60]

Yeah... umm... I changed the o2 sensors and go figure, I kinda forgot which wire goes into which plug. I have the front 3 cylinder (closest to the umm... front) o2 sensor plugged in the rear (closest to the driver) plug. Am I right or wrong? In any case my check engine light is staying off heh. But I feel as if I lost some power, but maybe I've gained it back. I'm not sure.

Can't they only connect in one direction?

I'm pretty sure you have them in the right way.



If I recall correctly, the O2 sensor closest to the firewall (driver) plugs into the socket closer to the front of the engine. That's how I remember it being when I did mine.
