Hi senior members. I have a 1995 E300D with 253K miles, a 1991 300E, a 1992 400E, and a 1993 400SEL. I do all my own repair.

I have a question. I need to know where the Convence control unit is located in the 1991 400E. I have a picture from the Mercedes repair CD but there is no landmarks around it to know where it is on the car.

Thanks Hal
