Unknow Right rear wiring connector identification

[Hobbes]

Can someone please help identify what the two connectors are for in the attach pictures. They are part of the right rear (passenger) body wiring harness that sits in the engine compartment. I don't have the male connectors for either plug. The engine is a 2002 3.6.

Thanks.

The bigger one you can ignore. It's supposed to be unplugged and it's used only for diagnostic purposes.

The smaller one looks like for fuel injector but many other sensors use that same BOSCH connector so I'm not sure.

The bigger one normally snap on a plastic bracket close to the right rear lamp.

Thanks. I double checked the all the injectors and all are connected when I put the engine in. the connector wire is not very long and I 'stretched' it out to see what it touches and all the places it did come in close proximity didn't have a place to plug it in. With the little bit of oil on it, I thought it was on the engine, but still no luck. Durametric isn't throwing any error codes. Right now, I'll assume the one doesn't have a purpose, but I'll look some more.
