speedo sensor
 

I changed the title cause I did not get much to this post: http://www.peachparts.com/shopforum/tech-help/53912-speedo-flaky.html
Can any one tell me where the speedo sensor in a 1991 560sel is.
thanks

May be the same. . .
 

I don't know if your year is different, but the speed sensor for the speedo/odo in a '86-89 560SEL trans goes into a hole on the left side of the case, near the rear, about 2/3 of the way up from the bottom. It's about the side and shape of a cigarette lighter.

The connector marked "A" on the harness shown at http://www.carcentric.com/speedoharness.jpg is the speedo/odo sensor I'm referring to.
