    Hi everyone,

    I am trying to rewire my 2002 tundra ltd 4.7.

    Can you please share insight on my problem. They stole my catalytic converter, along with that they cut the bank 1 sensor 2 hardness leaving the wires hanging. I bought the female plug, just don’t know how to rewire it correctly.

    I got the catalytic converter replaced however they failed to install the right sensor plug hardness and well it was running on a bank 1 sensor 1 where bank 1 sensor 2 belong.

    I purchased this plug from eBay.

    And

    OEM Denso Sensor from Amazon

    O2 circuits sometimes don't play nicely to being spliced, unfortunately, and you can see circuit-related errors just because someone has used shitty methods to reconnect the wiring in a way where resistance on the wires is not equal to OEM expected. i.e. using wire nuts, butt splices, quick-taps, etc.

    Likewise, scAmazon often sells counterfeit parts, they have no control over their supply chain (not only that, RockAuto and other places are usually cheaper). I'd never trust auto parts from them, too many people here have gotten fakes, some incredibly authentic looking ones. Others, pretty obviously generic/white-box. fleaBay is equally bad, if not worse. I've gotten personally burned on that one, and seriously burned with appliance and small engine part on scAmazon.

    Anyway, that out of the way, what exactly are you looking for? Wiring schematics? Service manuals? Links to both are found in the first couple paragraphs over here.

    Sorry you were a victim of cat thieves. Scum of the earth.
