I not sure if this helps or not as I am not familiar with the "plug and play", but are the "Breaks" in the outer rail of the 5" sections both located on the same side and opposite the Lock-on. Also if you are trying to lengthen the distance the gateman is activated, you have to either purchase a straight section without the bar on the underside of the track that connects the two outer rails or you have to remove it on the current one.
