Soak wooden skewers in water 30 minutes.
Preheat grill to 350° to 400° (medium-high). Thread turkey and next 3 ingredients alternately onto skewers, leaving 1/4 inch between pieces. Sprinkle kabobs with seasoned salt and pepper. Stir together molasses and vinegar.
Grill kabobs, covered with grill lid, over 350° to 400° (medium-high) heat 12 minutes, turning after 6 minutes. Baste kabobs with half of molasses mixture, and grill 3 minutes. Turn kabobs, baste with remaining half of molasses mixture, and grill 3 more minutes or until done.
