That would confirm my thinking then - I will take a look at mine with a torch and see if i can see it - I dont have c/c either. Cant promise to remove my mainfold to look for you though!
i really need to get my old copy of WIS working again (havnt had it installed since i sold my CLK). no idea if it will have my 1994/1995 W124 info on it though. Can anyone confirm?
