I've searched the net looking too see if anyone has done this. I've came up empty. But I haven't put a ton of time into searching either. Work has been crazy. I want to get rid of the 5202 housings because the way the bulbs clip into them is a pain and one of mine is currently broken. There are places that sell the same exact housing for the nnbs Silverado but they take a 880 bulb. I'm assuming the 5202 wiring harness doesn't plug into a 880 bulb but I don't know for sure either. Has anyone done this swap? Thanks.
