Warning message displayed in instrument panel advising to check rear right hand side marker lights, on initial inspection in the truck their was a smell of burning plastic emigrating from the right hand side rear light cluster on removal of the fuse panel cover and inspection the wires which connect the wiring harness to the lighting backplatei I was unable to hold the connector with a naked hand due to the excessive temperature. After leaving things to cool down for 60 minutes I was able to remove the wiring harness connector from lighting cluster back plate to find that the earth pin (brown wire extreme right hand side ) was melted and also the pin to which it mated too had also began to melt the plastic which supported the pin on he lighting back plate. The earth (brown wire) is of an extremely low gauge for the potential load this wire would potentially need to carry under maximum load (all lights lit).
