Well I made a quick FOG light wiring harness for the silver Colorado today and had a question.. Amberado is mailing me her OEM fog light connectors and so while I was waiting on them to arrive I started on the harness. The OEM's show black and purple coming outta the connectors. I assume black is ground but wanted to make sure so I knew when they get here. Shouldn't matter but I have seen wires grounded to the chasis of the fog light housing in lieu of the bulb socket. SEE attached pics. The only remaining line to run is from the passenger side fog to the driver fog. Should make the install go alot quicker though. Many thanks for any input.
