So should I try and eliminate the green from the taillight, it seems to be just soldiered on the inside

So my bracket broke off for my tailights and im busy replacing flickers. However I cannot get them to work. I connect the two black ground wires to a terminal that runs to all the other grounds, which in turn have a wire that grounds to negative terminal of battery. Coming out the tail light is another green wire that splits with two points for connecting the other flicker wires, and runs into connector box as per pic. All the grounds are connected and run to negative terminal. When I switch indicators on, Either one flashes and the tail light flashes, or both front flash with tail light.I replace relay box, checked all bulbs are working and tested continuity with all grounds. I've got to the stage where I took the entire loom out and it now sits on my dining room table.very frustrated as I am not very electrically inclined but determine to figure it out. Please help
