[Phase I: Dash Kit Integration]
Metra Dash Kit: 2007 Nissan Altima Kit (99-7423)
Metra Wire Harness: 2007 Nissan Harness (70-7552)
Metra Antenna Adapter: 2007 Nissan Aftermarket Radio to Factory Ant (40-NI12)
With all the metra products in hand, the head unit and touch screen were installed into the dash kit. The individual units were installed as two stacked ISO units. Although holes on the side matches the stacked ISO format, neither one would grab onto screws. Using a #10-32 thread tap, I enlarged and threaded holes that would allow the units to be mounted and screwed into the dash kit.
The wiring harness was the next step. Thourough soldering was done. The metra wiring harness did not contain the wires for the steering wheel interface, so I had to add wires into the harness for this. This is what is looked like after the extra wires were added to the plug.
The final wiring harness complete after two hours of careful soldering. It includes the car adapter, screen wiring, headunit wiring and the PAC audio device. The spool of red wire is for the 12 volt switched for the carputer itself. The wire still looks like a bit of a mess, but I decided to keep all the wires as long as possible incase I need to modify this later on.
