I have a 1995 Maxima GLE. I just got a new knock sensor and as I was installing I found a electric connector with a missing harness please help with I.D. i've included a pic should be easy to figure . The connector is in the lower left in pic light brown.

 

is the car running fine without codes?

if so, then chances are you've just got a connector that doesn't connect to anything...IOW there's an optional feature that your car does not have that plugs in to there.

 

The green connector appears to be laying next to the socket in that picture.

 

As for the brown connector, I would plug in the green connector and scan for codes. Usually that brown sensor is there for cars that have the BOOST sensor and I have yet to come across a 95 that has that sensor.

 

Yup, that boost sensor is part of the MAP circuit, which is what's disconnected in his picture.
