Hazard Switch Wiring Diagram

That's the one that the orange wire attaches to on the hazards which appears to be a ground and its on the outside which possibly means the ground for the illum of the hazard LED. 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.
