Does anybody know where this plug goes? Ive been pouring over the wiring diagrams and every time I think I think I have found it it ends up being already connected. It appears to be 1 of 3 green plugs on the engine harness. Its the plug in the top left that I am holding that I cannot figure out. This is the only plug keeping from finishing. Also posted this in the 3rd gen forum but I figure this is a better area to post it in. my car is a 1994 rx7
