I have attached a picture for you. If you need connectors like those in the picture then you can use the Hopkins Endurance Flex-Coil Trailer Connector Adapter with Nite-Glow, # HM47043. This adapter is designed for use when flat towing, 7-wire blade-style vehicle end connector and 4-wire round towed vehicle connector.

If you have a different style of connector, please send me a picture and I will be happy to find a product that will work for you.

To get the correct connectors needed you could create an adapter consisting of the WesBarg 7-Way RV-Style Connector with 6 Ft Coiled Cable, # WG54006-043, and Pollak 4-Pole Round Pin Socket, # PK11410, which are shown in picture #2. A premade 7 way to 4 way round male adapter is not available. Since there isn't an industry standard wiring diagram for the 4-way round connector, you will need to use a circuit tester like part # 3808 to determine which pins have which functions on the female side that you will be connecting to. From there you will then attach the corresponding wires to their respective pins on the male side of the connector. The green wire from the 7 way will connect to the pin on the 4 way (# PK11410) for running lights, red wire to left turn pin, brown wire to right turn pin, and white to ground.
