My trailer lights aren’t working. Metering the vehicle 7 pin plug socket, when I test the common pin and constant power pin I get A solid 12 volts. When I test common and left and right directional and brake pins, with the directional and brakes on I don’t get anything. I metered all fuses related to towing and they are all good. I tested the towing tail relay and it tests good. The harness connection to the towing socket is nice and tight. I’m at a loss. Any ideas?
