Ok...I am very new to Tacoma and to top it off not much of an electrical guy. First the set up...I am running a 2011 Tacoma with the 2.7 l, 4 cyl engine. I just bought a second hand Leer cap. Now I want to wire the 3rd brake light thats in the back of the cap (above the door). Which wires do I need to tap from the brake light assembly..? The cap also has a white cargo light in it. I would also like to tap a wire to power that as well but my my main concern is the 3rd brake light for now.
