Thanks so much for the picture. It looks like you're wiring up the Pacer Module # PP20-702 to a trailer side 7-Way connector, which you then plug into the 7-Way on your truck to power the topper's lights. I was able to zoom in on the connector you're using and the issue appears to be that the yellow and brown wires are simply attached to the incorrect pins.

On the connector, the pin where you have the brown (running lights) wire attached is labeled "BLACK", which is reserved for 12V power. The yellow wire next to it is then attached to the pin labeled "BROWN", which is for running lights. Basically all you need to do, if you're looking at the picture you attached, is move each of the wires (the brown and both of the yellows) one pin over, clockwise.

This will then match the circuits from your truck's 7-Way and everything should work perfectly on the topper's 3rd brake light. Just let me know if you any issues still persist.
