I did the same calculation and came up with this 2 ohm resistor. It worked but the wiper was a bit slow so I changed to a lower resistance, maybe 1.5 ohms. I would need to take the car apart to check, but somewhere around 1.5 is a good starting point. The keys are just for scale. There are plenty available on the internet.
