Which is the primary 02?

I unhooked them both, and now I forget which is which..lol.

One has an orange sleeve, and the other has a grey sleeve.

I am not using the secondary o2 anymore.

Thanks

........ circle in a square hole lol trial and error. Although I believe that they are both four wire heated o2 sensors so wiring clips aside they are the same.. dont quote me though.
