So the 1jz i'm messing with has 1 blue and 2 black wires for the oxygen sensor, no connector. The colors for the o2 sensor connector (wiring harness side) has a red, white, and black wire.

Which wire goes where? I'm sure the two black wires can interchange, more concern where the blue one goes. Thanks

Red-blue wire is heater positive (to one of the black wires).
Black-red wire is heater ground (to the other black wire).
White is sensor signal (to the blue wire).

Thank you sir. I didn't want to assume that, but figure it would be considering it was the top wire out of the triangle plug.
