Hi, I need a engine wire harness as well as the body/to started harness for my 1996 e320 convertible. I am told the 2 door coupe/convertible has different wiring harnesses to the 4 door?? is this correct or is it compatable with other 320 mercedes eg s-class or sl320 etc just im having problems finding one so would like more flexability!! any one know where i can get these at a reasonable price used? thanks :-)
