A new Mercedes-Benz Ponton cable harness
Above you can see parts of the new cable harness (some parts, like the rear branch, are already installed in the car). This harness was ordered from Krieg Kabelbäume in Germany. It looks exactly as the original Mercedes Ponton cable harness; every cable is cut to correct length, has correct color coding and is provided with correct terminals. When you order it you can even add new cables as per request. In my case I added cables for the radio, for glove as well as engine compartment light, extra cables for the trailer hook I have - and may install - and also a hazard light function including the extra switch. Verrry neat.
Before installing the harness I needed to perform a couple of things:
- Understand and verify all cables and their connections, that the harness was correctly built
- Clean up, reconnect and verify the new cable harness to the fuse box and to three cable sockets, for the tail light harness, for the steering spindle cable and for the heater blower cables
- Solder and verify the socket on the main cable harness for the instrument cluster
I suppose the galleries below are self explanatory. The first shows the fuse box and the different sockets. The screws in these sockets where still in very good shape and hence not plated (the screws in the steering cable socket is brass and hence not plated).
The second gallery shows the resoldering of the main cable harness' instrument cluster socket. Took some time verify all the connections on the main cable harness as well as its connection to the tail light harness. For the soldering of the socket, please also see Instruments and switches.
If you have made reparations of the battery floor and the partition-/firewall, maybe my sketch of the layout of all the holes in the latter may be handy when it comes to route the cables from the coupe into the engine compartment. You can find it in Instrument panel, floor, parcel shelf, window frame (67, 68, 69).
