A method of determining whether a blind plug for a trailer connector of a trailer electronic braking system is correctly installed. The trailer ECU can detect the presence or absence of an electrical connection between first and second pins on the trailer connector. A blind plug is provided, which provides the electrical connection in the installed position. The trailer connector may be compatible with SAE 560:2020, ISO 1185:2003, 7638-1/2:2018, 11992:2021 or 12098:2020 and may be substantially weatherproof. The plug can be used as part of an end of line test and have a warning light which is activated via the CAN bus or powerline.
