Re: What are these?
the middle one is to add or release tension on the throttle lever....so if you let go it stays where it is instead of falling down and the motor throttling down.
if it is too tight it is hard to control push the throttle, if too loose it would be like a car gas pedal...you let go and you slow down.
the connector MIGHT be for tilt and trim...many motors dont have it...but the control is made to be used with all motors...
and the TNT uses three wires many times.
good luck
