FiTech EFI system

I know it's been asked before, but I didn't read a strait answer and want to double check with my set up. I'm going to run timing control, and wiring the system with my MSD box. My question is where are all you guys running your white acc. wire. I just want to make sure I'm getting the Acc. Power when cranking.

Any constant hot 12V, that includes crank and run.
some guys have been pulling a choke wire. others source the fuse box.
