QuestionHI KEVIN , I HAVE A 98 RAM 1500 WITH FACTORY WIRING AT THE HITCH FOR A 7 WIRE RV CONNECTOR. THE TRUCK END WENT BAD AND IM TRYING TO REPLACE IT WITH AN AFTERMARKET BRAND PLUG THAT WILL ACCEPT 7 WIRE RV AND A 4 WIRE SMALL TRAILER PLUG.
COULD YOU PLEASE TELL ME WHAT THE WIRE COLORS ARE FOR THE MARKER LIGHTS, 12 V CHARGE LINE, ELECTRIC BRAKE POWER. FOR SOME REASON WHEN I PUT THE TEST LIGHT TO THE WIRES I CAN ONLY GET THE BRAKE LIGHTS AND TURN SIGNALS, AND REVERSE LIGHTS TO POWER UP THE TEST LIGHT. IM LOST HERE WITHOUT A WIRING DIAGRAM.PLEASE HELP IF YOU CAN, OR GUIDE ME ELSEWHERE.
