hola
creo que te refieres al sensor de temperatura del motor hidraulico...
si es asi dicho sensor esta interno dentro del motor y sus cable salen juntos a los testigos de escobillas...creo recordar que son de color azul y rojo..se distingen por la funda que es de goma

Translation...hello
I think you mean the hydraulic motor temperature sensor...
If so, said sensor is internal inside the motor and its cables come out together with the brush indicators... I think I remember that they are blue and red in color... they are distinguished by the rubber sheath
