Mix jerk seasoning, brown sugar, corn oil and lime juice in a bowl. Pour over cleaned shrimp and mix.  Allow to marinate for at least half an hour.

Place shrimp, pineapple, and red onion and red pepper pieces onto skewers alternating between the shrimp, pineapple, red onion and pepper.

Grill kebabs for about 3 minutes on each side or until the shrimp is cooked.
