i bought a bosch oxygen sensor (part # 000 540 52 17) last year for my 95 c220 only to find out that this "oem" sensor has a different connector with the mb's. i have called many parts shop and they all told me this is the one for my car. fastlane did not display the part number. is there a seperate adapter i need to buy or this one i got from the mail was a wrong one in the right box? thanks
