Called the parts department at my local Honda Dealer.
2006 Civic Si Wiring:
Postitive = Light Blue/Grey
Negative = Pink/Grey
As I said in my previous post. The colors for the blue modular connector (harness as everyone calls them) can be confusing. There are two blues on it. True Blue and Light Blue...
(EDIT)One other thing about T-Taps. There are several varieties of T-Taps. Some that connect Perpendicular and some that connect Parallel to the wire.. I suggest getting the smallest sized (NOT AWG size) you can (such as the parallel ones). Those wires are in there tight

.. Infact.. I've bought both styles (two different trips to find stuff for this DIY) I'll take pics of both
