converting my wiring harness, have some questions....XFI

[BLACK MAGIC RACING]

I have a custom main harness made by caspers for a classic fast, and I'm trying to convert it to xfi. I just need some clarification on the pins. I'll be using a distributor and am msd crank trigger, which pins do i use? the harness was set up for factory ignition and cam sensor. Also, grounds. A1, A2, A12, C11, B7, D1, D8, B25, D12, D15 are all in the pinout chart marked as grounds, and are not accounted for in my originl harness. Do i have to ground them all??

Where did you buy the xfi from? If you bought the xfi from us. Give me a call and I'll get you sorted out. My cell phone number will be on the back of the xfi.
