Just got my OEM fog light switch which I will be wiring to make work for my fogs, but without connecting to the BCM. Took a quick glance at it and it has 4 prongs. Might take a trip to the junkyard to see if I can at least get the connector from the dash of a car that had fogs. Anyone have a schematic of what the 4 prongs are? I'm guessing power, out to BCM, ground, and LED, but don't know which is which.
