it might be so that the brake wire is for a 3rd brake light, i was just going on how the wireing diagrams/ instructions that came with the kit says to do it. i may end up having to modify it a lil to make it work the way i want it. id try some of the ideas to test this wireing but i found out today the turn signal switch is broken, due to previous owner instaling an aftermarket wheel and f***ing everything up. but i have my brake lights hooked up so i can drive it, i just have to be careful when changing lanes or turning, since i dont have blinkers. This car has turned out to be alil more of a mess then i had expected for a first project, but their is no better way then to learn, besides im the only 18yr old in west palm with a nova. :D
