My car looks like it's going to be running tomorrow, my downpipe isn't finished yet, it ends right after the oil pan. I haven't got to put any O2 bungs yet so I'm wondering what the best to do is. I do however have 1 o2 bung on the turbo's O2 housing. Should I:

Leave both O2's disconnected

Splice both O2's to the one O2 sensor in the housing

Wire only the primary

Thanks, which ever method I do I'm probably going to "blue wire" tap into it and check to make sure that I'm running safe.

just hook up the primary first so the car doesn't go in to limp mode
