R-Design steering Wheel

[IMAY2023]

My S60 2019 US model has the green connector and the three wires on the gear shifter which then goes to the main center console connector. 
The Center console is connected to the main dashboard harness. That Harness did not have the three wires from the SWM to the center console harness connector. 

I had to rewire the SWM to the Gear switch green connector to make them work. 
Again with VOLVO saving money for the tree wires. I really don't get this logic. If the goal is saving money, why have the wires on one part (center console) and  don't have the other hand. 

Maybe it's the US cars only I don't know.
