It sounds like you are trying to go from a 7-pole to a 7-blade trailer connector. If the 7-pole is on the vehicle and the 7-blade is on the trailer then you will need to combined the stop and turn signals with the Roadmaster Brite-Lite Wiring Converter part # RM-732 and then just install the Pollak Black Plastic, 7-Pole part # PK12-707E after the converter.
