This component is part of Electrical Systems.

Definition

The connectors used in the Mercedes-Benz wiring are made of hard plastic, and consist of a box with room for round pin bushings, intended to be soldered to wiring, and a cover. Most of these are still available new from our well known suppliers. They were used in many different forms (round, rectangular and even triangular) with a varying number of posts: anywhere from 2 to 14. Clearly the connectors with 14 posts are actually quite expensive.

Function

For a detailed look at the wiring of the system, visit the Wiring Diagram.

The document below lists all connectors, pinouts, and colours of the main wiring circuit. If one of your connectors has broken and you need to hook it up again, this document is essential.

Even though this document states it is not for the 280SL I have found it to be correct for most connector pinouts I've done troubleshooting with, and until there's a better source document, this is the most useful we have. The reader beware, it may be incorrect.
