I ordered sensors (front and rear) because one of my devices accidentally fell out. I tried to connect them to isolate them, which didn't work. After removing the wheel and accessing the connector, I found that the ends of these sensors were the opposite of what I needed (other people seem to be having the same problem). None of the sensors (front is different than rear) fit my 2000 car plug, despite the website saying so. Of course they can't be returned, so $15 down the drain. Be careful with URO parts, they are counterfeits of poor quality and workmanship and it seems that those who sell them are no less suspicious.
