C-9 Goes to the small terminal on the starter. ( tells the computer when the starter is engaged)

C-2 You can just disregard this wire.
D-1 Is a system ground. I just ran a main ground for the computer system and grounded it at the back of the head. (Pass. side)

You are right there is not an A-7 wire but there is an A-5 and this is your ses light. It is a ground the the cpu turns on when it needs to. I just used my choke light and put a switched 12 volts to one side and then wired in A-5 to the other side. works great.

A-6 as you said is pk/blk. It ties into sevral places in the harnes to give switched 12 volts where needed.

As for the fuse rating I think stock is 10 amp.

For b-1 I used a inline 20 amp fuse.

as for A-4 it is just a ground from the cpu to turn on the egr relay. so a fuse is not needed.
