Mark,

These are switches used for the emission controls that are used in the North American market.

Hi Mark,

The information you seek is on the MB CD.  Its a little hard to find.

If you can't find it or don't have the CD send me an email at jclute2012@gmail.com and I'll mail it to you.

Br,

Jeff

The diagram is in the big blue book but I currently am not able to attach. If you do not get this by the weekend I will scan and attach.

These switches are only found on standard trans cars. There's a switch for fourth gear and one for third gear. When you're coasting down hill, or from a higher speed, they will turn the injection pump to the off position. The reverse light switch is on a seperate harness.

Mark,

The diagram for the 280SL manual transmission emissions is on page 00-78/3 of the BBB.
