ok guys like the title says i need help converting my dual point fuel ingection ( throttle body injection( 2 injectors)) to a multi point fuel injection harness

if some on here can either guide me through it or point me towards a site that has a thread on the subject that shows step by step how toos that would be great

my original plan for my sedan was to use my crs mpfi harness and just lengthen the nessicary wires but i found out that this will not work
