Place turkey in a large resealable plastic bag. Combine the next five ingredients; pour over turkey. Seal and refrigerate for 8 hours or overnight, turning occasionally.
Drain and discard marinade. Grill turkey, covered, over indirect heat for 1-1/4 to 1-1/2 hours or until juices run clear and a meat thermometer reads 170°. Meanwhile, combine sauce ingredients in a saucepan; cook and stir over medium heat until thickened, about 5 minutes. Serve with the turkey. Yield: 10 servings.
