Hi, I am in the process of fitting a non-original cruise control to my '88 250 Turbodiesel wagon. I had this particular unit installed in a w123 and it worked great - however, the back of the speedo is different on the w124, and there is already a sensor fitted. This little devil goes by the name of VDO 007 542 29 17 and has a + and a - marking on two of its three connectors. The last, much fatter one does not have any markings - is this the one to use for the lone wire from my unit (the w123 required only the one wire and a chassis connection)...?
Any help would be appreciated!
Kind regards from overseas...

mottakelse,

('Couldn't find any Danish on "Free Translation" , Norwegian might be a standby?)

VDO-Siemens
Speed Control Sensor; Idle/Cruise Control Impulse Sender at Rear of Instrument Cluster.

In "View 1", in the picture, the large pin on the left?
That's the speed sensor output for the Cruise Control.

The other two pins are Power (positive) and Ground(negative).

I don't know why the sensor is "Powered".

Terminal 15 is Positive
Terminal 31 is Negative

Hi and thanks, this is perfect - I am already warming up my soldering iron...! Don't worry about the lingo, norwegian works just fine....

The firts links page you sent me didn't work, probably because I use Explorer with all the @#4!!!€ pop-up-blockers, I'll install a free-ware browser and look again. Thanks a lot for your fast help, I'll be back with a running report!
Regards from sunny Denmark (21 degrees centigrade and a fresh wind...)

Best Freeware Browser.(above)

Compress ignite, you're the man! The cruise control, although not MB-original, now works perfectly - thanks a lot!
Best regards from Denmark (18 degrees centigrade, heavy showers all week...)

That right foot gets tired on long drives without it.
