I followed (attempted) this design, but I've made a mistake. It will only go if the brake is pressed as well. When the brake is pressed the brake lights come on and everything else works exactly as it should. I just can't figure out my mistake on this. The brake, tail, and reverse are all within one unit, so they share the black wire. Any help is greatly appreciated.
