So, tried to search and found plenty of info. Im wanting to double check as Im a little confused. Okay, is this correct: this is what I have left

C207
Pin C check engine
Pin D fuel pump
Pin K speedo
Pin M VSS/P/N Grd
Pin N ECM/ P/N switch

Do I need both M & N or just one.

C221
Pin A & D are my injector fuses. So I connect them to my pinks on my new injectors?

Then do my Coil pink wire's go to new fuse holder?

I just finished decoding my C207, and I have an '84 Trans AM. It was frustrating, because the wiring changed over the years. I had to search each pin and do lots of reading to determine if I needed the connection. Check out post 14 on my build thread:

I bought a "Pocket Prepped" C100 and C207 plug for 89' Iroc with manual transmission. I just wanted to see how the stock wiring was modified since I've never done this before. Only 5 wires were utilized on the '89 C207, but your '86 could be different. I'm only using 2 wires from the C207 on my '84.

Thanks for the info!! I think I might just start swapping in my 9" and get fuel system setup. Wiring isn't too bad, especially with all the info out there, but it's kicking my butt. Not sure how many wires go to starter and alternator, which gauge, whatnot. Almost basic stuff I should know. I'm getting there, and I usually would throw the towel in and try and get a buddy to do it, but I'm determined to do it myself. Heck, the LS harness is done and 3rd Gen is done and I've got both in car, just need to make those connections.
