Flat vs. Round Trailer Connectors
- Flat connectors are for everyday towing, a secure fit and easy installation.
- Round connectors are for heavy-duty towing, a robust connection and are often used for larger trailers and off-road applications.

Securing Your Trailer Connection
A trailer connector is only as good as its installation. To keep your connection strong:
- Use high-quality wiring and terminals – Cheap components can cause voltage drops and unreliable performance.
- Regularly inspect and clean connectors – Dirt, dust and corrosion can interfere with electrical contact.
- Tight fit – Loose connections can cause flickering lights or brake failure.
- Weatherproof covers – Keep dirt and moisture out when not in use.
