    My rear o2 sensor is bad so i bought a new one, factory denso brand, but it doesn't come with the plug so i will hardwire it.

    The wire colors are different too.

    Can anyone be kind enough to check their truck and what color corresponds to each on the different sides of the connector?

    The new sensor i bought has blue, white, black, and black.

    My wiring harness has brown, black, red w/ whitelines, and white w/red lines.

    My truck is a 99Prerunner if that matters.

    Thanks! :D
