Hello all, I have a 72 Maverick with a C4 column-shift transmission. I cannot figure out why my reverse lights won't come on. I've replaced the switch mounted to the column near the floor, and the bulbs check out okay too. I originally thought my adjustment was off, but at no point in the selector's travel do they actually come on. Where does the wiring for these things run? Could it be bad wiring, or is there something I'm missing?
