GsLex02

Hello everybody, I am hoping someone can help me with this zero point calibration since it is pretty simple. My problem is everything I have read says use terminals 4 and 12....however in my 2002 Gs300 there is no metal prong inside one of these terminals. Someone else had the same issue back in June but his question was never answered. Can anybody help with the terminal numbers needed to do this calibration on a 2002 Gs300? Thank you.
