Can the throttle lines of electric vehicles be directly connected together?

All right. The electric car has no throttle line, but there is a speed control line on the controller. The electric handle of the electric car is in the right hand, and there are three wires leading to the controller. One end of a straight line is on the handle and the other end is on the throttle plug. As long as the nut is tightened, the throttle line of the electric vehicle can be directly connected.
