    Hello all,

    While grinding rust off my frame I managed to rip apart my O2 sensor connection. Now I don’t know which wire goes where. Would love some assistance.

    Cheers,

    Here's a wiring diagram showing the O2 sensors. Looks like most of the wires are red and some other color.

    The diagram is for a 1998 Tacoma. Maybe it will help???

    unfortunatly those wires are for the A/F sensor itself. I did take a picture of mine but without the pin/plug orientation it is worthless. You might have to stop by an auto parts store and look at a sensor and snap a photo.
