so where did all the wires go from your OEM harness that once went to that big injector plug on the Vortec engine? Can they all be removed from the harness or do I need some or all of them for other things now?

Also, does anyone have any feedback on what happens with the EVO sensor on the PS pump? My truck has this steering assist sensor and Im not sure where this would now tie in to the 411 PCM
