See attached excerpt from TSB 14. His description of the wiring and circuit breaker seems to indicate that this modification has been done. I don't know why there is a difference in the location of the yellow, green, brown and grey wires between figures 18 and 19 but I am assuming that at one time the lights worked as wired and that somewhere along the line the power wire from the breaker has become unhooked from the relay. by the way, the relay coil wiring in fig 19 is not correct. It shows that both terminals of the coil are connected to power. The black wire should be jumpered to the relay coil unless internally jumpered.
