Ok, the top card is your system card. There is a rectangular board piggy-backed onto the face of the card. That is your VFC. Below the VFC the should be 2 small cards plugged in that are sticking straight out at you. If you look on top of these cards, one will have 5 little transistors and the other will have 8. These are called CD5 and CD8 as they are coil drivers. I beleive it's CD8 that controls your aux functions. Try swapping that first.
