Good morning. I have a quick question. Does a 1985 300SD have a tachmeter sending unit? I see the sensor at the flywheel and I follow the wire to the diagnostic plug and then the 2 wires disappear under the fuse box. Am I looking in the right place of it? I remember reading that the 84-85 year did not have this. If someone could help me out, it would be much appreciated. Thank you.

David
