Give item on belt/wear/main

Hi!
I use this

Code:

player.GiveItem(ItemManager.CreateByName("supply.signal", 2));

to give items. But how can I do to give an item to specific container like belt/wear/main?

Thanks.

 

Code:

player.inventory.GiveItem(ItemManager.CreateByName("supply.signal", 2), player.inventory.containerMain);
