2002 Toyota Camry O2 confusion

Hello, recently bought a replacement O2 sensor for my 02 Camry, however the connectors are different; the one ordered have four pins with a plastic in between 2 while the original has the same plastic except for it is like a little t’ sticking out.  I’ve provided a pic of the original to be replaced.  Is there a specific sensor I need to order that has this connection?  Is there a specific wire harness an aftermarket one since it doesn’t connect with the OEM(supposedly) replacement?  Many thanks in advance!

Hey Aprendiendo369! Merry Christmas!

For our info, which engine does your '02 Camry have? What was the part number of the sensor you ordered? Are you trying to replace a downstream or upstream sensor?

Taking a shot in the dark based on photos from RockAuto, it looks like you're holding a downstream rear O2 sensor. Most of the replacement sensors I can see have that same little 'T' in the middle of the connector. Can you post a picture of the replacement sensor connector for comparison?
