Hi All,

I am trying to diagnose some problems with my new 1992 300d. The Mercedes manual calls for a Contact Box (MB # 124 589 00 21 00) to connect to certain plugs (the SRS system in this case). Can I do this without the box? Is it wired so that pin 1 on the plug is pin 1 on the Contact Box? Has anyone made one or a reasonable copy?

Thanks so much,

Andrew Moore

Check towards the bottom of this page - K6JRF Auto Page You might be able to fabricate the switch and LED device used to read fault codes.

If you're diagnosing an SRS light in a 92 300D, start with cleaning the contacts in the slip ring between the steering column and steering wheel.

The contacts on the column are the cluster on to the upper right -



The contact set can be replaced as this assembly with blue sleeved wires and red locking connector -

You are the man! It was unplugged!

Just for reference, it was showing SRS codes:3,5,6,8.

Thanks.
