my japan import 2008 non nav doesn't have the steering audio controls but looking at the pinouts on stereo unit and infiniti circuit diagrams Im wondering if the harness will still be there and retrofitting factory parts is an option.

it has been done on infinitis along with retrofitting the gear paddles but I wondering if the japan specs ones are degraded in any way.

I have an NM35 Stagea Which also didn't come with the steering wheel controls.

When I fitted an aftermarket cruise that I bought through #Commsman; he supplied it with a pair of wheel controls to suit my OEM wheel.
They fitted up no problems, and the clockspring, which carries the cabling for airbag & horn, also carries the wiring for the audio & cruise control switches.

The only issue you are likely to have, is at the other end of the steering column where the wires come out.
The plug from the main harness does not have the wiring to connect up the controls, but you can remedy this by using the pins from a disassembled PC harness plug (which Commsman kindly supplied to me) to make up a harness, and connect to your compatible stereo. Push the pins into the harness plug in the correct positions, and you have a factory looking harness and plugs.

The controls only use 2 wires, each essentially providing a bunch of varying resistances to the controller; which usually has to be "taught" by memorising the resistance values for each specific function.
