The harness is your problem, unless you added the plug for the knock sensor. D series engines don't have one, so you'll need to add the wiring.

 

daym ya'll.. another day of trial and error, but nothing seems to work
i juss added the knock sensor line like you guys told me too but still no difference.. the check engine light is gone so i kno my wiring was okay.. no check engine light goes on now, but motor still bogs and sounds like shit... i tried both my ecus, P28 stock & p72 chipped Skunk2 still nothing works, motor still sounds like a lawn mower .. PLEASE HELP , AGAIN
