By putting the light into #3 you were effectively providing power to the components that run off the asd relay. The noises are a good sign that that part of the wiring is indeed connected.

The lack of power to either hot terminal at the relay starts to point towards a failed fuse link. These go between the battery and fuse block. Normal test for a fuse link is to pull on it, if it stretches, its burnt.

Follow the positive cable to a point where 5 or 6 wires are spliced to it. Those will likely be the fuse links. Start at the battery. You may have more than 9ne bad link, I don't know if the same one provides power to the asd and ignition switch.
