Up-to 3 years ago, I owned an '83 300S. I always wanted a remote starter but every specialist I spoke to told me it could not be done. finally I found a shop that assured me that they they can do it. Six Hrs. after starting the installation, they could not get it to work and gave-up. They charged me nothing, and chalked it up to experience. The problem was not so much in starting the car remotely, but rather, getting it to shut-down afterwards. The major obstacle seemed to have been the Vacuum Shut-Off Valve. They just could not get it to work.

About a month later I was parked besides an '81 300SD (Like yours) in a Mall parking lot, when all of a sudden the vacant car stared on its own. I could not believe it. When I asked the approaching owner, if he was happy with his remote starter, he said that he is extremely satisfied. He than proceeded to give me a demonstration. The car started and shut-off flawlessly.

However, when I asked him who installed it for him he had no clue. He apparently bought the car used, and the remote starter was already installed.

Go figure.
