Hey Guys,

I was hoping one of you could help me out, I have a 2015 Ram with the 5.7 and am looking for information on the correct orientation for the 02 sensors. There appears to be a white and a black plug on the ends of the 02 sensors which corresponds to a matching receptacle on the truck, I am confused as to which one is the up-stream and which is the down-stream sensor, any help would be appreciated.

Thanks :favorites13:

Upstream is closest to the motor. Is that what you're asking?

I am trying to figure out which color plug (white/black) is the up-stream one on each side.
