HEAT barbecue to medium-high heat.
PLACE 4 long wooden skewers, side-by-side, on clean work surface.
THREAD shrimp onto sets of 2 parallel wooden skewers alternately with pineapple, peppers and onions. (You will have 2 kabobs.) Mix barbecue sauce and ginger until well blended.
GRILL kabobs 4 to 6 min. or until shrimp turn pink, turning and brushing occasionally with barbecue sauce mixture.
