ok, i pieced together all the information and realized that all that was really involved to do the keyless part of it was to send power into the unit and the to figure out which wire would do the lock / unlock. apparently on the w124 it's that blue wire that's connected to the vacuum pump. i could brobably go in the trunk but i hate having to do trial and error since nobody seems to know about the connections back there for the w124. i picked up a jcwhtney keyless entry that says it has built in relays and works with vacuum pump systems. i will be sure to post my results...
