Kenwood head unit - steering wheel controls

[chalmene]

Vehicle: 14' 370z Sport (non-bose, non-nav)

Stereo to install: Kenwood DNX995s


Needing some answers from someone who has installed this head unit, or similar. Yes I've been all over the forums, Youtube, and product manuals and seem to come up with mixed results.

I bought the Axxess ASWC-1 module as recommended by Crutchfield to retain steering wheel controls. (side note, this module did not come with the programming buttons or lights as described or in videos, and seems to be self-programming)

Questions:

The Kenwood DNX995s wiring harness comes with a wire labeled "steering wheel remote input". Can this be used directly with my car's stereo harness without the Axxess module?

If not, can someone give clear instructions or a diagram on how to wire in the Access module?
