Trailer Wiring Connectors

Trailer wiring connectors provide the electrical connection between the tow vehicle and trailer. Depending on the towing setup, this connection can carry circuits for trailer running lights, turn signals, brake lights and other trailer electrical functions.

Connector configurations vary considerably, so identify the connector style and electrical requirements of both the tow vehicle and trailer before ordering.

7-Way Trailer Connectors, Plugs & Sockets

7-way trailer connectors are commonly found on RVs and larger towing applications. Depending on the vehicle and trailer configuration, a 7-way connection can support multiple trailer lighting and electrical circuits.

Our inventory may include replacement 7-way plugs, vehicle-side sockets, trailer-side connectors, adapters and related wiring components. Always confirm the connector configuration and terminal arrangement required for your application.

4-Way Trailer Wiring Connectors

4-way trailer connectors are commonly used for basic trailer lighting connections. Available products may include replacement plugs, sockets, harness components and adapters for compatible towing applications.

When replacing a connector, verify whether you require the vehicle-side or trailer-side component and compare the existing wiring configuration with the replacement product.

Trailer Wiring Adapters

Trailer connector adapters can provide a convenient way to connect compatible tow vehicle and trailer wiring configurations when the connector styles differ. Adapter configurations vary, so both sides of the connection should be identified before selecting an adapter.

Depending on current inventory, this collection may include adapters between common trailer connector styles as well as replacement plugs, sockets and other towing electrical components.

Choosing the Correct Trailer Connector

Before ordering a replacement trailer wiring connector, plug or adapter, determine the connector type on both the tow vehicle and trailer. Check the number of pins or contacts, vehicle-side versus trailer-side configuration, wiring requirements and manufacturer specifications.

Vehicle-specific wiring products should also be confirmed against the applicable year, make and model. For universal components, compare the electrical configuration and connector style carefully before installation.

Trailer Wiring Brands & Replacement Parts

Our trailer wiring catalog includes products from established towing and RV parts manufacturers, with available brands and connector styles varying by current inventory. Individual product listings provide the manufacturer part number, specifications and available fitment information to help identify the correct component.

For electrical repairs beyond the trailer connector itself, appropriate wire, terminals and related electrical components may also be required depending on the installation.
