i saw a while back at a nissan meet. a guy with an s13 hatch sr. when u looked in the engine bay u didnt see any wires and he said that he deleted most of the useless shit like u r talking about. i dont know who he is, but someone has to. i would deffinatly try to find this guy and ask him for help. he had a pretty good grasp of knowledge on the harness. just a thought
