[white20gfwd]

i am trying to help my friend hook a apexi afc in his 90 prelude si with alb. we cant find what wires are what on his ecu. we have looked all over the internet and at the local parts shop but there not any help. if anyone can help us out it would be a great help. we know what the wires are for the apexi afc but have no way of knowing what wires to tap into.

See if Honda can get you an ECU wiring diagram/ pin chart. If you're nice, one of the Honda techs might copy a page from one of the books for you.

we tried to go to the local honda dealer but he seemed not to have it any place. its almost like the car was never made. what in ny are you near?
