A) An this one? That goes to the cable leaving the AC compresor, the two blacks are for the dual fans
the others i dont know, but plugs are unique you cant fit them in another plug so no error, only have to look for the right plug i guess.
I dont recall any white plugs under intake, only one black to the AFM
b) is a connection for the 'cleaner control' relay(headlight washers?) which you appear to be missing(would be about under your hand in the pic)
c) the only wire i have in that area is for the washer pump motor
d) definitely for the cruise control actuator
saco- they're already gone and im finally going to finish this project, its been almost two years since i pulled the na engine and dropped this one in. so im kind of walking in the dark- minus you and the other helpful forum members.
