First I'd like to thank mercedesshop for the quick responses to my questions, they have been very, very helpful.
Now I have a speedo question. Speedometer & Cruise were working fine, then while driving the speedo went dead. Not really sure where to start. I know there is a control box under the dash, and the wiring harness that goes to the tranny. But after reading the postings, there seems to be several other areas involved as well. If someone could offer up a starting point to begin eliminating possibilities I would really, really appreciate it.
Thanks for your time,
