I've had to rewire the trailer lights feed (12N) due to the connector being trashed (don't ask!)
When trying to connect it the lights weren't connected correctly and the brake lights were flashing when the indicators were on. Since then what I can only assume is the indicator towing buzzer is continuously sounding (it's in the boot and is the same pitch as it was when the indicators were on previously).
Does anyone know why the buzzer is on constantly? And how to stop it?
Any help very gratefully received.
