i'm having a problem, whats the difference between a 89-91 mass air harness to compare to a 92-93 harness?? i've just talked to a guy who says he has a 92 mass air harness, he sent me pics of it, and it looks just like mine (89 mass air harness) except, where the computer plugs in, it don't have the green plug, mine does, also, at the firewall, coming out of the driver's side, where the engine harness connects to the main harness, how many plugs should there be? my 88 has 2(1 grey, 1white), and on my 92 lx 4 cyl. i have 1 grey, 1 white, and 1 red(brownish). i'm just lost, does anyone have a pic of what a 92 mass air harness looks like at the driver's side where it connects to the main harness????
