Expert Reply:
The Adapter 4-Pole to 7-Pole and 4-Pole # 37185 will allow you to connect the 7-way round blade plug to your vehicle with only a 4-way flat connector. Do understand that any electric brakes, reverse lights, and charge line will not be able to get any power with this type of connection.
If your trailer connector has round pins inside the connector you will need the Custer Trailer Connector Adapter - 4-Way Flat to 7-Way Round # KIT-7P-4. This kit again will not include wiring for electric brakes, reverse lights or a charge line.
The Wiring Kit # 5506 will allow you to connect additional wiring for a charge line and Brake Controller # 90195 with either adapter above.
