While I guess it is possible that it would work, you are asking for a nightmare. Even if you did want to give up a key (which you would have to do and leave it mounted in a ignition sensor transceiver under the dash) and wanted to got through having the wiring in the truck messed with, you are asking for problems down the road. A high end stereo shop I deal with regularly said he would not even try it on my 99 430. The security system and interlock system is so complicated, and MB is so tight lipped about what wire does what, he did not want to start cutting into it (and said I should not try either). It is the one BIG downside to owning an MB in a colder climate.
