If you check our wiring section of the site, you could get good pics of the PSX connector there. When you buy the lights they do not come with a harness, everything is built into the actual light, so all you have do it is unplug the factory light, and plug these in the same connectors. We built the lights from the start to accept and work with JK's so they have the proper electronics built into them.
The lights come with enough wire to fit into most aftermarket bumpers, even the ones which outboard the lights from the factory spot. The lights come with around 16-18" of cable on them usually. If more was needed for a specific reason we could always add a tad bit as well.
