RV Pigtails 20020 4-Flat to 7-Way RV Trailer Wiring Adapter

The RV Pigtails 20020 is a wiring adapter that converts a 4-flat (4-pin) vehicle connector to a 7-way RV-style connector, allowing you to connect a trailer with a 7-way plug to a tow vehicle equipped with only a 4-flat socket. This adapter is essential for towing smaller trailers or cargo carriers that use 7-way connectors with vehicles that have the more basic 4-flat wiring system.

Key Features:

• Converts 4-flat vehicle connector to 7-way RV-style output
• Enables connection between mismatched trailer and vehicle wiring systems
• Durable molded construction for weather resistance
• Provides basic lighting functions including running lights, brake lights, and turn signals
• Compact pigtail design for easy storage when not in use

Important Note: This adapter only converts the physical connection and passes through the four basic lighting circuits available from the 4-flat connector (ground, running lights, left turn/brake, right turn/brake). The additional circuits on the 7-way connector (auxiliary power, electric brakes, and reverse lights) will not be functional without those circuits being present on the vehicle side.

Ideal for recreational vehicle owners, this adapter provides a simple plug-and-play solution for trailer connectivity without the need for permanent wiring modifications.
