How about with that TS harness connector halves seperated, you jump fire to the green wire in the downstream half of the connector & see if the green wire behind the drivers kick panel is hot which I'm sure it ain't now but that would for sure pin it down to somewhere inbetween those 2 points. I ain't up on how the hazards are wired/interact with this & someone had posted a pic of the TS harness & where each wire goes to but I dont know how to access it. Opens happen at the terminals/connectors/switches so just me I would take a peek at mymopar for the diagrams then grab my meter & I ALWAYS pull a batt cable BEFORE switching the meter to ohms (& you will do voltage checks also). Short version: I would start at the TS harness (green wire) & work downstream.
