LS3 starter wiring?

[jlwdvm]

I a have been plugging away on the wiring on my 69 firebird track/street car with an LS3 and AAW Power Plus 20 wiring harness. I ordered a pigtail for my LS3 GM starter, but don't know which wire off of the fuse block to run to it. I'm used to older GM starters/wiring that has an "s" and "r" post.
