The Narva 5 Pin Large Round Socket On Car To 7 Pin Large Round Plug On Trailer adapter lets a car with a 5 pin socket run a trailer that uses a full 7 pin round plug. You get standard stop, tail and indicator wiring handled through the Narva layout, so lights stay in step with the tow rig. It is a smart buy if you swap between smaller trailers and ones wired with extra pins.

The housing is solid plastic built tough enough for regular towing runs, with metal contacts sized for typical trailer light loads. A spring flap covers the car end to keep dust and grit away from the pins when you unhook. The length gives you something to grab without smashing knuckles on the tow bar. It is straightforward gear that helps you get out there and tow without rewiring the whole setup.

Q: Does this adapter change the trailer wiring from 7 core to 5 core?

No, the adapter only links the 5 pin socket layout to the 7 pin plug layout. Any pins that do not exist on the car side will not be powered on the trailer side. The adapter passes through the available light circuits but cannot add extra feeds. If you need all seven functions you will still need a matching 7 pin socket on the vehicle.

Q: Can I leave the adapter connected to the vehicle all the time?

Yes, you can leave it in the vehicle socket if you wish. Many people keep the adapter fitted so the tow bar is always ready for a 7 pin trailer. Just check the flap still closes properly to keep dust out. Removing it when not towing will reduce wear on the socket and adapter.

Q: Is this adapter suitable for basic trailer lighting only?

Yes, it is suited to standard trailer lighting circuits. The unit is made for stop, tail, indicator and similar low current functions. High current accessories like battery charging lines should use dedicated wiring. Keeping it to light loads will help the adapter last longer.

Q: Will this fit any standard large round Narva trailer plug?

Yes, it fits standard large round Narva style plugs that follow the common Australian layout. The car end uses the matching large round socket pattern. Always check your existing plug is the large round type and not the small round variant. A quick visual comparison to the photos usually confirms the match.
