It will mostly work but there are some connections you will need to make yourself. I don't remember them off the top of my head but VTEC solenoid and knock sensor come to mind. It's been discussed many times though so searching may give you the answers you need. As far as I am aware it is pretty rare for people to swap harnesses when they swap VTEC engines into LSs, given the cost and difficulty of doing so.
