I'm trying to do trailer wiring for the Chevy Express 3500 that I bought a few months ago. I came across an unused 12 pin Molex connector mounted just above the rear bumper. I assumed this was for trailer wiring, but I can't find anything that appear to use this connector. Does anyone have any idea what this is for? It has a part number of 33472-1206 printed on it....which turns out to be a specific model of 12 pin Molex connector.
