There are actually 7 wires, but it's no biggie. Once you get past the apprehension of cutting into the harness and soldering inside your car it's pretty straightforward. Luckily I'm a :ninja: with the soldering iron.

The only bit of weirdness is the fact that the wire colors are different in the FX than they are in the 350Z, so the wiring diagram Unichip gave me didn't apply directly. I was able to verify however that though the wires are different colors they occupy the same pin locations in the molex connectors. Very minor issue in the grand scheme.
