Thread necromancy, but....
The clock spring you need is 8619-A017 - the one on the car is either this one (US models with CC and/or media controls) or 8619-A016 (horn only) - you can get it on Aliexpress for about US $10
8619-A018 looks almost identical but has an incompatible airbag connector
the other 8619-series modules aren't physically compatible
If you want to create a heated steering wheel (2amps required) you'll need to be prepared to do a lot of customisation but the good news is that an arduino should fit into the back of the steering wheel assembly if you wanted to repurpose the 2 resistive signalling pairs for other purposes
It's worth looking at https://iserv.nl/files/pics/imiev/ardui ... i-MiEV.htm
