on my 96 SL 500 not all the pins are wired on the diagnostic connector. Only 11 out of 38 have sockets?? Pins wired are 1,2,3,4,6,10,11,13,21,23,30. Since pin 7 has the electronic accelerator this will make troubleshooting th EA very difficult. I have ABS & ASR lights on rough idle with occasional cut out stalling at idle warm only. Sound like a EA since 96 cars have the good wire harness,.But this is an expensive part to throw at a car for troubleshooting purpouses? any sugestions? I do not think the LED code reader works on 38 pin cars. Thanx John.
