So in my FSM diagram the ammeter and ignition switch are fed from the unfused side of the fuse panel. The hazard switch is powered from the unfused side since it junctions off the alternator feed. The turn signal switch, turn flasher and stop light switch all receive power from the fused side. Since the original lights on this rig "should" have been the single round units then copying the FSM diagram for wiring should provide hazard lights without the converter being required. Am I following you?
