Thanks! I just swapped mine out. Nigel had one! So I discovered that the black one that was hanging beside my harness was the feed to the headlights. Also while connecting the new harness I found 2 very bad wires. I’ve replaced them with crimp on heat shrink connectors. The new harness end has 2 red wires instead of just one in mine. All others were identical. I just taped off the extra one. Not sure what it’s for
