ok so I am doing my wire tuck an I forgot to label a connector. I am pretty sure it goes somewhere towrds the back of the motor. Its for a 92 gsr. Its a 4 wire an the colors are.
Green/White
Yellow/Black
Orange/Black
White (with a black thicker shielding)
Sounds like the O2 sensor plug but I would need a picture to verify.
Heated oxygen sensor, it is the only sensor with 4 leads, and they are the correct colors. 94
