your diagram is just what I'm talking about and I have both built and purchased them. The talk about other relays far away does not make sense as locating a relay at the far end of a thin wire can't be correct and has no value. Sometimes a car company builds a relay in but more often, like Chrysler, Ford, Jeep, and others ( z cars) it is cheaper to skip. It is a valuable upgrade when you have very poor headlights, as US model 240's do. Thanks!
