An electrical connection validation system 22 is provided for a tractor 10 and trailer 12 combination, which typically is for travelling on roads such as one with a fifth wheel. The system 22 checks for a correct and working electrical connection between the tractor 10 and trailer 12 and is for systems such as braking. The system 22 has a trailer connector comprising an electrical connection 20 typically having seven electrical contacts, which may include pins. A sensing wire 24, 26 is connected to each contact and a controller 30 is connected to the sensing wires and to an alert means 32 and is configured to issue an alert signal, for example an LED visible alert signal, when the improper connection of any of the electrical contacts is detected. LEDs may be green or red and may flash according to the number of improper connections. A remotely visible positive signal can be provided if all contacts are properly connected. an alert signal transmitted to a fault-reporting system such as an onboard telematics device. An improper connection can be reported remotely via telematics.
