Hi , I've recently bought a 2019 Lexus NX and it doesn't come with keyless entry function that I like it pretty much , I've found this solution

That uses mobile phone as key , when you approach the car it unlocks it (it have the function of remote start but for me is not very interesting) , the installation instructions don't look very difficult

But i would appreciate any wiring diagram / video to easly find the cable under the steering wheel area (the 12v , the open /close cables etc)
Do you know where i can find it ?

Thanks
