Hello, when I bought them from theretrofitstore.com they were plug and play
Since you bought another brand/set you probably know if this is the connector. Here is a close up of the XB LED connector. Does it fit your harness?
These are the newer model (LF111) the ones I am selling are the LF110, but the connectors are the same: https://www.morimotohid.com/morimoto-wrangler-jl-xb-led-fog-lights?quantity=1
