I got some fog lights from Amazon and they are supposed to be plug and play but they aren't. Here's their connector (left) and mine, are they wrong or is my wiring not standard somehow? My JKU didn't have any fogs at all when I got it so I can't compare.

 

The plug on the lights you got (left) are definitely not factory. It's been a long time since looking, but I do believe that right is the factory harness.

 

Sounds good, time to contact the Amazon seller and see what they say. It's just weird that some of the reviews say they plugged right in...
