sorry for reposting but does anyone know which is the primary oxygen sensor for a b16a1? is it the green plug or the yellow plug?

 

if memory serves me correctly, the white plug is the primary sensor.

 

haha .. well here goes nothing .. thanks

 

you'll know if it's backwards because it will not run as well. the most you will loose is a few minutes in swapping the wires.

 

the white or sometimes yellow plug is the primary, it is the one that will fit in your wire harness plug.

 

That is what that is. I just purched a 88 CRX Si and when I was cleaning out the engine bay I found the "Yellow Plug" with about six inches of wire. I dident know what it is BUT now I know it is the primary o2 sensor. How should I go about re-installing this wire?

Should I just splice both wires and twist them together and plug it back in?

Does anyone have a detailed instructions on how to reinstall this?
