hang on a minute, i just helped a buddy put the same motor in a 94 CX hatch, i wire o2 sensor, prewired for vtec etc and some of the o2 things were already ran to the ecu. the dx and vx and cx are different lolz at that mess. why i have no idea. my book is on del sol's, let me see if i can find a link for a chiltons for you and you need to follow the diagram and look at the ecu pin out on IA and in the book to compare. it can always be straightened out, just need to look for the best and easiest route, don't want a rats nest of wires.
