But that's odd because the ground on the outside for the s-mode illum is a really small wire like all the main harness wires are. The big wire I'm talking about is solid black though. Since all my body panels are off you can see every ground bundle of 10 or so all over the car are all solid black wires of different thicknesses.

In practice, it doesn't really matter. The bigger the wire, the better, but the current through the light is minimal and the current through the switch is almost zero.

When I say "good ground" I mean "low resistance ground".
Do you have a schematic/diagram showing how the switch is wired internally. One of the switch terminals probably powers the light (internally) and the third leg is the ground for the light, but, w/o a diagram, impossible to be sure from here.
