Replacing a plug/connector

I decided to clean all sensors connectors and when I took apart the knock sensor from the holder went into many pieces and I got left with all plugs in my hand, good thing, I was able to put them back into the female plug that is (color blue). I went to the dealer but I do not know if that is the correct part number since twice in the past they give me wrong part numbers this is what they give me: the knock sensor #39250-37150 I saw it on their screen but is not a blue color and other is if that is the part that I do not know how to connected since the short wire goes into somewhere under the intake I guess, my first thought was to change the male plug but I need a female plug to match and having a problem to look for something like that needs to be able to handle three wires.
I do not have an engine light and it is working good, but I think eventually I need to get to it and looking for good prices around and get all the information for me to be able to change it. Can you let me know please! Will appreciate all of our help to do it the easy way. The last picture shows the connector with a electrical tape for now, next to the other gray connector. Thanks a million.
