You spelled trunk wrong three times or you have a truck car. You are doing LCD with cloth wiring. You are describing colors/stripes of wire that means nothing to us. You are talking about wires "coming back" to fuses like the fuses are somewhere in the back of the car.
You now have one brake light wire that lights both brake lights. THAT MUST BE CHANGED to two separate brake/turn wires (left and right, operated by, and thru, the turn signal switch). You have one wire for both your driving/tail lights and license light (all connected together and operated by the headlight switch). That is OK. ................ two + one = 3. Provide/change/add/modify/redo the necessary wires to the rear and wire the T/S switch per instructions and you are done.
Many of the online diagrams showing the 7 wire turn signal wiring don't really show three wires very clearly. They show one for left, one for right and the third is hard to see because it DOES NOT come from the turn signal switch. Some diagrams say "rear tail lights not shown". Some say "existing tail light wiring unchanged". Some don't show or say anything because they know you have tail light wiring and they are just showing how to wire the turn signal switch.
