I recently got a 1992 prelude with an h22a swap as a little project and it runs a little off. I checked over everything and amongst the horrid mess of spliced wires I noticed that the map sensor had nothing plugged into it! Upon further inspection I noticed that there was nothing in the engine bay to plug into it! I am severely confused as to how this even happened and really need help figuring out what to do since this is my first Honda with a swap and I am not sure how it can just be completely missing that wiring. Any help or ideas would be greatly appreciated.
