Default O2 Sensor connectors -which one?

I'm ready to connect the O2 sensors from the exhaust, and I'm looking at the two connectors on the chassis. Which connector is for the pre-cat O2 sensor and which one is for the post-cat one? It looks like the connectors are the same.

One should be black and one should be gray.

Thanks Tech! I supposed if wasn't pissed off like a deranged psychopath after wrestling the angle drive back onto the trans because I couldn't re-attach the down pipe without doing so.....I might have seen it myself.

No - I was "simply" swapping transmissions. It's a fairly low miles (130k) '98 that was in decent enough shape to fix. And I found a decent donor/parts car that wasn't in decent enough shape to fix. This will be a flip car to help get 3 kids through college.
