2.Wire :
See the wire.jpg pic.
P.S. I use the 3.7V battery set for the power supply.So the Vin should have Voltage(smaller) close to the power of battery set.
P.S.Here's a point, I use Vin to connect the 12V sucket of L298N, because it's more stable than you connect from battery set (or ets..).And it's enough for your RC car.
