7-Pin Round Trailer Plugs
The large round 7-pin connector is the old-school Australian workhorse. The metal shell and screw-together back shell make it tough and easy to service, which is why it is still common on farm, industrial and older box trailers.
Supplied, wired & converted on-site

Pin functions follow the common Australian standard. Older or custom trailers can differ — we always test before we terminate.
