    In my own imaginary world, where. Respect for wome
    So I swapped out the rear (downstream) o2 sensors on my truck yesterday. prolly will swap out the upstream in a few weeks, just to be new all over. as usual, i ordered my parts from Rockauto. I went w/ Motorcraft parts (they werent that much more than generics). I was pleased to see that they were shipped w/ anti-sieze already on the threads. the electrical connections are color coded so you can't put an upstream module into a downstream port. Purple is down stream. Grey is upstream. All I used was a crescent wrench. Make sure to disconnect your battery when swapping these out. Took me 20 min to swap both of these out. And onto the pics:

    Here are the plugs, w/ the driver side already removed.

    This is a great post mate, i also have this universal car oxygen sensors that i just recently bought and it has a manual. I wonder if this is compatible with my truck. They said that it is compatible when i asked them when im buying it.
