Wiring Diag for Speedometer
 

Does anyone have a wiring diag. for the speedo / speed sensor for an '85, 500 SEL german import (grey market). The diagram on the MB electrical troubleshooting manual I have (USA version) does not match the wiring on the car. The speedo has a round black plug on the back, with two blue wires, one on a black sheath, the other plain. It also has an intermediate connector on the blue un sheathed wire, then a short blue lead (approx. 2-3 in.) to the speedo.
