Neither red wire should go to the striped side of the cap, but rather the unstriped side.
If you run the red wire to 13L, it will be very close to the 0.1R 5W resistor. Since the jacket of this wire is not as heat tolerant as the PTFE on the rest of the wire, it is connected at 7L to move it away from that heat source. These two terminals are connected together with a piece of wire, so they are electrically equivalent connections. If the look bothers you, you can move the red wire on the other side to 21L.
