I Posted a thread back in June 2023 about my taillights issue and I got no help. I have a 2007 E350 Base and basically what’s happening is that as my auxiliary lamps turn on, my brake lamps do as well. Even if I’m driving and not hitting the brakes, the brake lamps are on but not the third brake light. It’s annoying because I like the look of the auxiliary lamps paired with the DRL headlights but the brake light annoys it and kills the vibe. I tried to get into the wiring setup but I know nothing when it comes to electrical stuff. Can someone help me figure out why the brake lamps are connected to the auxiliary lamps?

Brake pedal NOT engaged

Brake pedal IS engaged

A wire running to the harness jury rigged to the brake lamps
