RE: Cruise Control for 280GE
I'll put up a diagram in a few days.--
I have had the system for 3 years. No problems. It is electronic based and as such, it does not use vacuum, so it provides a full throttle response.
You will need to add the factory cruise control "stalk" switch. This is a standard switch which fits both G's and was also used in many of the late 1970's through the middle 1980's cars such as the "123" chassis (ex - 280E, 300D). I recommend getting a switch from a car dismantler which saves cost as compared with buying a new switch from the dealer. Get the two switch attaching screws as they are a bit longer than the screws currently in your steering column.
The stalk switch wiring harness ends in a rectangular shaped electrical plug. It helps to also get the other side of the plug from the car the switch came out of along with a few inches of wiring from this other end to use to connect to.
Your steering column was designed to fit this switch and it installs right on the factory location using the same mounting location that is currently used to attach your turn signal switch.
