Alright guys, i've got a 2g universal o2 sensor with no plug on it. It came with an o2 housing i bought a while back so there were no instructions. It's been so long since i've installed one of these universals that i've forgotten what colors on the o2 sensor harness go to which on the harness. The sensor wire colors are Black, Black, White and Blue. The harness side colors are Yellow, Red, White and Black. I am assuming that the 2 bigger wires (black and white) are for the heater, which should attach to the 2 black wires on the sensor, and the red and yellow are for source and signal, and that they should attack to the blue and white on the sensor side.
