    Sensor does not come with document to identify what wire color does what function. I was able to find that online. However with new terminals crimped on, the sensor would not function and did not do any switching. I bought another Denso sensor that came with a connector already installed and it immediately started working and switching properly. Buyer beware, I think the sensor I got was a dud.

    If you can cut wires and put them securely together, you can save money

    I'm very pleased with this purchase and save a lot of money. I saw several comments from people complaining about the missing connector. The description states that there is not connector, if you don't want/feel you want to do this type of work don't buy. I bought it 'cause I can do it and it was not a major issue securing the wires to the old oxygen sensor connector.

    Denso sensors work great!

    If you are confident with wire splicing these are a bargain. Make sure you leave enough heat protective wrap from the old connector to be overlapped with the new wrap. Staggering the splices is it necessary if you want to fit them inside the wrap. You could put the spices all together if you are not sure how to stagger them and keep the lengths even. I siliconed the ends of the spices for corrosion protection. It's a bit of work but it saved substantial money doing all four O2 sensors.

    Not a oem like I ordered

    This product works like it should . But I was disappointed because I order oem and got a universal instead and had to make it fit which took more time. Did not have time to send it back. Rick
