That looks like the Add-GM24. The wire at B3 is the one to tap for an amp trigger, but it probably isn't white in that harness (it's white on the oem C1 harness that plugs into the back of the radio, IIRC it's usually pink on the Add-GM24).
The Add-GM24 will plug in between the C1 plug and the back of the radio, giving you easy access to the new wires without having to actually splice into the oem car wires.
C6 radio prints are HERE if you haven't seen them yet. When looking at the C1 plug pinouts, remember that you're looking at the inverse of the female end of the harness you're holding, and an exact copy of the male end.
