[MTA][DayZ] Adding a vechile

Hello there people, basically the title ask's you what i would like assistance with, i got the um complied version of the script so i'm free to add new vechiles, edit and add new back pack slots ect.

I asked him to make a TXT document explaining how to add a new vechile, and he give me this

OW TO ADD NEW VEHICLES 
  
1) Set a definition for the vehicle in vehicle_spawns.lua and coordinates for spawnpoints of vehicle 
EXAMPLE (for Hustler): 
  
hustlerSpawns = { 
  
{0,0,3}, 
  
} 
  
Hustler in the example above will spawn in x=0, y=0, z=3 (Blueberry Acres). 
  
2) Search for function called "spawnDayZVehicles()" in vehicle_spawns.lua. 
  
3) Search for "[NEW VEHICLES!]". That's where you will insert the code for your new vehicles. 
  
4) Copy and paste this: 
  
    for i,veh in ipairs(hustlerSpawns) do 
        local x,y,z = veh[1],veh[2],veh[3] 
        veh = createVehicle(545,x,y,z) 
        vehCol = createColSphere(x,y,z,1.5) 
        attachElements ( vehCol, veh, 0, 0, 0 ) 
        setElementData(vehCol,"parent",veh) 
        setElementData(veh,"parent",vehCol) 
        setElementData(vehCol,"vehicle",true) 
        setElementData(vehCol,"MAX_Slots",20) 
        --Engine + Tires 
        local tires,engine,parts = getVehicleAddonInfos (getElementModel(veh)) 
        setElementData(vehCol,"Tire_inVehicle",math.random(0,tires)) 
        setElementData(vehCol,"Engine_inVehicle",math.random(0,engine)) 
        setElementData(vehCol,"Parts_inVehicle",math.random(0,parts)) 
        --vehicle_indentifikation 
        setElementData(vehCol,"spawn",{545,x,y,z}) 
        --others 
        setElementData(vehCol,"fuel",60) 
    end 
  
5) Tables are scattered across the whole script, called vehicleAddonsInfo and vehicleFuelInfo. 
Search for them. 
  
  
vehicleAddonsInfo: 
{ID,Tire,Engine,Tank Parts}, 
  
  
vehicleFuelInfo: 
{ID,Fuelloss per minute}, 
  
  
6) Adding aircrafts and more helis is currently bugged and results in a corrupted database as well 
as increased network trouble for clients. 

I do understand a few things but, i'm no LUA scripter, and as ive said before i havent got the intelligence to learn.

If some one could make a document for me, explaining step by step what to do to add rustlers and new cars ect it, it would be amazing.

Thanks.
