I'm back to post wire harness pics.

First pic is what the Metra kit provides:

- Large red connection is compatible with the OEM connection in the RX-8
- Small white connection plugs into the interface box that came with the Metra Unit.


2nd Pic in the album:

- The Metra harness soldered to the Kenwood DDX419 wiring.
- Small Black connection goes into the back of the DDX419 head unit.

After all the "dirty work" of color matching & soldering--the wire joining is not easy for guys like me with slight color blindness--luckily some of the cables have TINY descriptions along their sides.
