Thank you everybody for your invaluable suggestions.

Thomaspin, your web site's MBZ informations are really good. Pictures are worth thousand words. I have book-marked your web site.

In the mean time, I still have some questions:
(1) If I am using remote start mechanisim, how do you stop the engine if the engine accidently got started running. This could be very dangerous, that's why I want to be ready for it.

(2) By turning the bolt in front of the power steeling, will it turn the engine. If it does, I will have an assistant doing that while I am looking for the drain plug.

Thank you

Steve
