Modulescript not being called upon properly?

I've been working on a game based around having first person combat with like swords and such and decided it would just be easier to have a tool modulescript to work faster but I'm having difficulties

local _T = {}

local Players = game:GetService("Players")
Tool = script.Parent

function _T.ThirdPerson()
    Players.LocalPlayer.CameraMode = Enum.CameraMode.Classic
end

function _T.FirstPerson()
    Players.LocalPlayer.CameraMode = Enum.CameraMode.LockFirstPerson
end

return _T

that is the module script and my code to call upon it is:

local Players = game:GetService("Players")
local ToolMod = require(game.Workspace.ToolMod)


Tool.Equipped:connect(FirstPerson)

Tool.Unequipped:connect(ThirdPerson)
