My Z came with new style PTU. I replace it with brand new PTU the whole kit. If you look at the kit it come with new wire connector and relocation kit. I want to know if the six pins connector on the PTU control each individual coil pack connector? As in sending current through the coil pack connector and into the coil pack to make the spark plug spark. If one pin is not working then that coil pack would not get any spark. Thats what I wanted to know. Thanks for your help.
