I just swapped heads and used the harness from the new head. There are 5 plugs on each side but only 4 of them have a match. I have one wide white plug coming from the engine side of the harness that doesnt match up with the remaining yellow plug on then inside/dash half of the harness. I got the head from TooRisky so I'm not positive what year its from yet. I'm gonna call him and see if I can find out but for now here are some pics of the two plugs that dont match

if you go to the album each pic has a short description or if you can tell which plug is for what just by looking at then here are the pics without a description
