Harness works perfectly. For those trying to see it connects to the black connector on the other side of the green connectors, so you have to take apart the stock sub (see picture).
Great product. Noticeable difference in sound. Perfect fitment, even the screw holes are placed to avoid factory wires and other door/window components. The amp rack is a clean fit. And customer service was quick to response and resolve my issue.
Work as intended, found that I had to cut the bushings at the bottom and half and cut off some of the tab at the top due to interference on the Ford F150, lightning
