FAQs

Is this plug compatible with all caravans?

It is compatible with standard 12N 7-pin lighting systems, which are common on many caravans, but it is not intended for 12S (supplementary) systems.

Can I use this with cable larger than 8mm?

No, the internal design is specifically engineered for 7-core cable up to 8mm; larger cables may not allow the housing to seal properly.

Does this plug include wiring instructions?

The plug uses standard ISO1724 pin configurations; please consult a standard 12N wiring diagram for specific pin-to-wire color assignments.

Are the pins made of solid brass?

Yes, the plug features brass pins to provide excellent electrical conductivity and corrosion resistance.

Is this suitable for permanent outdoor exposure?

While the plug features a rubber seal for weather resistance, it is best practice to store the plug in a protected holder when not in use.

Troubleshooting

Lights flickering or intermittent connection

Check that the terminal screws are tightened securely on each wire and ensure the plug is fully seated in the vehicle socket.

Specific light, such as indicator or brake light, is not working

Verify that the wire corresponding to that light is securely fastened to the correct pin terminal according to the ISO1724 wiring diagram.

Plug housing is difficult to close

Ensure that the wires are tucked neatly inside the housing and are not obstructing the path of the rubber seal or the casing screws.

Pros and Cons

Pros

  • Easy to install with simple screw terminals
  • Conforms to industry-standard ISO1724
  • Durable housing suitable for outdoor conditions
  • Provides secure, reliable electrical contact
  • Cost-effective solution for replacing damaged plugs

Cons

  • Limited to 8mm cable diameter
  • Plastic housing may crack under extreme impact
  • Not suitable for 12S (supplementary) applications

Setup, Compatibility & Care

To set up the plug, strip the outer sheath of your 7-core cable, exposing approximately 10mm of each colored wire. Unscrew the housing to access the internal terminals. Following the standard 12N wiring diagram, insert each wire into the corresponding terminal and tighten the screws firmly to ensure a solid mechanical connection. When closing the housing, ensure the rubber seal is seated correctly to maintain its weather-resistant properties. For care, periodically inspect the pins for signs of oxidation and clean them with a contact cleaner to maintain optimal conductivity. Avoid dragging the plug on the ground, as this can wear down the pins and compromise the housing.
