Hey William. I have a solution for you but there isn't a simple adapter like item # 20142 in 7-way round configuration. Instead you will need to install the Load Resistor Kit for LED Turn Signals item # DI34ZR on all of the taillight circuits of your trailer that have LEDs. LED lights don't draw as much power as incandescent lights so a resistor is added to increase the amperage draw to resemble incandescent lights.
What kind of trailer are you pulling?

Hey William, how did things go with the load resistor kit for your trailer’s LED lights? Were you able to get the lights working properly with your 7-way round plug? Your update could make it easier for others running into the same issue.
