throttle position sensor questions???

[aparker5]

Just installed a twist throttle on a yfz and I am curious what the two wires that go into the factory thumb throttle do??? I cut them and connected them because thats what the motion pro instructions say to do but I am curious what they did in the thumb throttle. I think that they were for the throttle position sensor but I am still drawing a blank here. How does a throttle position sensor work and why dont you need one with a twist throttle???

If I'm not mistaken, you were thinking of the TORS wires. They shut off your engine if your carbeurator sticks wide open

and your twist throttle has return cable so it doesnt need them. your just completeing the circuit
