Thread: whats this connector?

the two ICM connectors are still on the 96 harness... someone told me they think it is the rear/ post cat o2 sensor. i will check when i work on the car today after work.

All the harnesses I've seen, the post cat was solid wired all the way to the cat..which is a serious length longer than that wire.

Which vehicle is this harness from?

Only things I've seen back there on a 3800 would be evap or cali emissions. Both os those are a two pin connector.
