My Bosch part off of ebay came yesterday. I had a real hard time getting the clip off. You need to push down on the part right behind the wire, I couldn't do it with my fingers, so I used a long screwdriver, and pulled the connector off with a pair of pliers. From there it went very smoothly & probably didn't take more than 10 minutes to pull the old sensor out & put the new one in.
My 1/4 in. star socket didn't work, so I just used a regular 1/4 in socket.
Thanks again guys.
