7-pole blade to 4-pole flat adapter. Use to tow a trailer with a 4-pole flat connector with a tow vehicle equipped with a 7-pole blade trailer connector. No cutting, splicing or tracing wires. Plug in connection makes connecting the two different connectors a snap. Adapts many late model factory "prewired" vehicles (including Jeep, Ford Trucks and Winnebagos) to the more commonly used 4 pole flat connector.
