This Narva 5 Pin Large Round Socket On Car To 7 Pin Flat Plug On Trailer adaptor steps a car with a 5 pin large round outlet over to trailers wired with a 7 pin flat plug. You plug the round end into the car and clip the trailer loom onto the flat plug head. The short body keeps the connector close to the towbar so it stays clear of chains and tongues when you get out there.

The housing runs a solid plastic body with metal contact pins rated for standard 12 volt trailer circuits. The plug and socket follow the usual Narva sizing so it suits most Aussie tow setups without mucking around. The moulded strain relief between the two ends helps protect the cable when the trailer moves over corrugations. It is simple gear that does one job well which makes it a smart buy for mixed trailer fleets.

Q: Does this adaptor add extra circuits beyond the original 5 pins?

No, the adaptor only carries the circuits available from the 5 pin large round socket. It simply changes the physical plug style to suit a 7 pin flat trailer plug. Any pins on the 7 pin side without a matching feed from the vehicle will remain inactive. Plan your trailer wiring around the active cores supplied by the car.

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

Yes, you can leave it connected if you tow often. Keeping it plugged in saves time each trip and reduces wear on the socket lid. Just check that the adaptor does not interfere with tow chains or recovery gear. Give the pins a quick clean now and then to keep contact quality up.

Q: Is this adaptor suitable for boat trailer use?

It can be used on boat trailers where the circuits match the 5 pin feed from the vehicle. The housing is typical automotive plastic and metal so basic rinsing after exposure to salt spray is recommended. Avoid immersing the connector during launch and retrieval where possible. Regular checks for corrosion on the pins are good practice.

Q: Do I need tools to install this adaptor?

No tools are required because the adaptor is a plug-in connector. You push the 5 pin round end fully into the vehicle socket until it locks. Then you insert the trailer’s 7 pin flat plug into the adaptor head. A firm hand push on each connection is usually enough. Always confirm all trailer lights operate correctly before driving off.

This adaptor suits vehicles fitted with a 5 pin large round trailer socket where the trailer uses a 7 pin flat plug. The gear installs between the vehicle socket and the trailer plug without wiring changes. The adaptor suits towing setups that require standard trailer lighting circuits through a 7 pin flat connector. Compatibility depends on the vehicle already having a functioning 5 pin large round trailer socket fitted.
