I have attached a photo of the Pollak Heavy-Duty, 7-Pole # PK11700 as viewed from the front with all of the correct wiring connections noted. 12:00 - White Wire is Ground. 2:00 - Brown Wire - Tail and Running Lights. 4:00 - Green Wire - Right Brake and Turn. 6:00 - Purple Wire - Reverse Lights. 8:00 - Yellow Wire - Left Brake and Turn. 10:00 - Black Wire - 12v Battery Power. Center - Blue wire - Brake Control Output.
The pin at 2:00 position is the correct pin that carries the signal for your running lights. If you check this with a circuit tester such as part # PTW2993 or equivalent, you will be able to confirm the function carried on each wire to determine where your issue lies. If the pin shows voltage, also check for bent, damaged or corroded pins within the connector, which can actually act as a short. ANY of these factors COULD interfere with the normal operation of your running lights.
I have attached two FAQ articles, ONE regarding basic trailer wiring that includes diagrams as well as one concerning troubleshooting wiring installations. Both of these may be helpful as you evaluate your malfunctioning running lights.
