Compatibility and Fitment
Match the existing connector to the Australian 7 pin DIN round layout before ordering. Do not confuse this plug with a 7 pin SAE or Euro connector, as the contact arrangement and matching socket differ. Compare the pin positions, socket shape and wiring functions before transferring the wires.

Compliance and Safety
Disconnect the electrical supply before opening or wiring the plug. Follow the supplied pin diagram, keep loose wire strands away from neighbouring contacts and confirm that the earth connection is secure. Reassemble the housing firmly and test every trailer lighting function before returning the vehicle to service.
Trailer Applications
Workshops fit this plug to electrical suzi leads connecting prime movers, rigid trucks and towing vehicles to trailers. It supports the standard lighting, indicator, stop, reversing, marker and auxiliary circuits carried through an Australian 7 pin round connection.
Why Choose ICS Trailers
Seven-pin plugs can share a similar appearance while using different contact layouts, so the DIN round configuration and matching socket style must be identified correctly. ICS Trailers can help compare the old plug face, wire colours and socket arrangement before supply. Send through clear photos of the connector and existing wiring when the original markings are damaged or the plug type is uncertain.
