PAC Outfit Entity

[EFEX03]

Hey guys I am trying to make an entity that when you press E on it, it equips a PAC outfit. I know that you have to do setup, but I am not sure where to put it in the file. I was hoping someone can point me where to put it. Here is the code:

AddCSLuaFile("shared.lua")

include("shared.lua")
local outfit = {
-- start of outfit.txt
    [1] = {
    ["children"] = {
        [1] = {
            ["children"] = {
                [1] = {
                    ["children"] = {
                    },
                    ["self"] = {
                        ["ClassName"] = "proxy",
                        ["UniqueID"] = "3120004463",
                        ["Expression"] = "hsv_to_color(time()*100)",
                        ["GlobalID"] = "4180875644",
                        ["VariableName"] = "Color",
                    },
                },
            },
            ["self"] = {
                ["UniqueID"] = "884479784",
                ["GlobalID"] = "1864536752",
                ["Position"] = Vector(0, 0, 28),
                ["Size"] = 2.175,
                ["Color"] = Vector(255, 12, 0),
                ["EditorExpand"] = true,
                ["Model"] = "models/pac/default.mdl",
                ["ClassName"] = "model",
                ["Name"] = "ball",
            },
        },
    },
    ["self"] = {
        ["ClassName"] = "group",
        ["OwnerName"] = "self",
        ["EditorExpand"] = true,
        ["GlobalID"] = "3872319760",
        ["UniqueID"] = "3296086797",
        ["Name"] = "my outfit",
        ["Description"] = "add parts to me!",
    },
},
-- end of outfit.txt
}

function ENT:Initialize()
    self:SetModel("models/Items/car_battery01.mdl")
    self:PhysicsInit(SOLID_VPHYSICS)
    self:SetMoveType(MOVETYPE_VPHYSICS)
    self:SetSolid(SOLID_VPHYSICS)
    local phys = self:GetPhysicsObject()

    phys:Wake()

    self.damage = 10
end

function ENT:OnTakeDamage(dmg)
    self.damage = self.damage - dmg:GetDamage()

    if (self.damage <= 0) then
        local effectdata = EffectData()
        effectdata:SetOrigin(self:GetPos())
        effectdata:SetMagnitude(2)
        effectdata:SetScale(2)
        effectdata:SetRadius(3)
        util.Effect("Sparks", effectdata)
        self:Remove()
    end
end

function ENT:Use(activator, caller)
activator:SetArmor(activator:Armor() + 10)
    self:Remove()
    activator:EmitSound("vo/sandwicheat09.mp3", 100, 100)
activator:addPart(outfit)

end

function ENT:OnRemove()
    local ply = self:Getowning_ent()
    ply.maxFoods = ply.maxFoods and ply.maxFoods - 1 or 0
end

This is the code I need to implement somehow:

if CLIENT then 
local outfit = pac.luadata.ReadFile("pac3/test.txt")

pac.SetupENT(ENT) -- this can also be used in initialize using "self" instead of "ENT"

function ENT:Initialize()
self:AttachPACPart(outfit)
end

function ENT:OnRemove()
self:RemovePACPart(outfit)
end
end
