Hey y’all does anyone know what color wire under the dash goes to the reverse lights , I have a 72 f250 c/s that had a utility box when I bought it I have since tracked down a color matching bed. Everything except the reverse lights work any info helps.

One I wired them onto a switch panel I had under the dash and had a issue with them grounding so to help I pulled the inner light housing out and added a small washer behind them and no problems after that
