Hi All,
Thanks for all the relies. As of this morning have eliminated the brake switch and any issues at the rear of the car. If I run a cable from the non live of the switch to the central pin on the main connector just inside the spare wheel space next to the drivers side rear wheel arch I have brake lights. Therefore the problem would appear to be between the switch and the main connector. I assume that the simplest way to repair this will be to run a new cable from the switch to the connector but any other suggestions on moving forward would be appreciated.
Thanks,
Dave
