Ok i did a search and didnt find anything on this. I have a 99 ex with a bad primary 02 sensor, so i picked one up from my friend off of his 99 Si. I was looking at them and they are a little different, they both have 2 black wires, 1 white wire, but mine has one green and his has one blue. Also the connectiions are different. The one on the car is a male connection, meaning the one off of my car is a female connection. But the 02 from his car is a male connection so it wont just snap right onto my car! I was told that i could just swap the connections over and sauder them back together! So my question is, can i really swap the connections and if so which wires go together! im assuming the blacks will go together and the whites will go together and then the blue and green will go together but i need to make sure! Thanks any help is greatly appreciated!

 

anyone?

 

Yes, you can just swap the connector from your old o2 sensor onto the new one.
Match all the colors, green=blue

Solder them together and use heat-shrink tubes if you have them.

 

thanks
