What is a South African Trailer Plug Wiring Diagram and How is it Used?
A South African Trailer Plug Wiring Diagram details the specific pin assignments and colour coding used for trailer connectors in the country. This standardized system ensures compatibility between different vehicles and trailers, simplifying the connection process and guaranteeing that the electrical signals from the vehicle are correctly transmitted to the corresponding lights on the trailer. The primary purpose is to illuminate the trailer's safety features, mimicking those of the towing vehicle.
These diagrams are essential for several key reasons:
-
Safety Compliance:
Ensuring all trailer lights are operational is a legal requirement for roadworthiness.
