Ok...but where does the socket get it’s ground from? Is the socket itself grounded? I don’t see that wire coming out of the pigtail...and I don’t see a ground wire in the wiring harness (3 wires...but none are ground).

All of this leads me to believe the housing itself is grounded somehow. The wiring diagrams from the forum even show ground from the light itself. Just not sure how it gets the ground
