we put in a 350x motor into a 250x chassis and the kill switch works but the head light does not work, we tried to see which color wire coming out of the stator " 350x motor " would give us power so we can just by pass it and hook it up to the head lights, but every time we touch a white or a black wire it kills the motor. please help we've been working on it for 3 nights and we can't get anything.
