Ok, I am working this as well and just want to make sure I have this straight. I have the 7 wire turn signal kit and it is wired as per the diagram that came with it. So now, running to the back of the truck, I have 3 wires. Two are for turn/stop and one each goes to the tail lights, left and right. The third, runs to both to run the tail lights. Does this sound correct?
Almost right. You should have one for left brake/turn, one for right brake/turn and one for both tail lights and tag light.
