Mira primero si hay derivación en la máquina. Por ejemplo en el motor de dirección. También puedes tener alguna derivación en los motores de tracción, alguna entrada de algún clip, por ejemplo. Lo mas importante mirar derivaciones.


Look here first branch in the machine. For example in the steering motor. You can also take a lead in the traction motors, one entrance to a clip, for example. The most important thing to look at referrals.
