How to enable cargo light and CHMSL

[toughawk]

Hello, I wonder if someone knew how to enable cargo light and central stop light on a 2014 3.6 ram, it Uninstalled from factory and it is a function I want to add, I upgraded headlight switch for fog lamp and cargo light, fog lamps works but cargo light only is on in the indicator closer but not in the central high mounted stop lamp.
Any help would be appreciated. Thanke in advance
