    I'm trying to fix wiring to downstream O2 sensor previous owner had done. Universal one was installed and now connections came apart so don't know what wires go to what. I found a thread noting which wires are which, but not sure what the codes mean. HT1B ?, OX1B ?, +B, E2 ?. Anyone can tell me which ones are which ? I know the universal O2 one white wires are for the heater, black is signal, and grey is ground. Any help appreciated.

    Scrubbed some tires, and knocked a dent out.
    Damn I wish I could think of the guy that knows everything wiring on here. Hopefully for you he'll be along here soon enough.
