Vice City: Multiplayer

Today, I found this store on 1 public server Store folder of Rockstar Experience Sprite (https://prnt.sc/1exC8jaVrc-i) and this script in script folder:
local g_LocalVehicle = null;

}And I want to bring the speedometer from this to my server (no need speed hint and stat text). But, I try copy and paste, editing the code but not bring me a answer (doesnt work).
I wish everyone help me!!!
My code:
main.nut in server side:
function onPlayerEnterVehicle( player, vehicle, door )
{
local stream = Stream();
    stream.WriteInt(1);
    stream.WriteString(vehicle.ID.tostring());
    stream.SendStream(player);

local vehID = vehicle.ID;
local vehName = GetVehicleNameFromModel( vehicle.Model );
local vehHealth = vehicle.Health;
ClientMessage("Phuong tien dang lai co ten: " + vehName + " [ID: " + vehID + "] Hien tai xe nay dang co: " + vehHealth + " mau", player, 255, 255, 255);
}

function onPlayerExitVehicle( player, vehicle )
{
local stream = Stream();
    stream.WriteInt(2);
    stream.SendStream(player);

}and the begin the file:
function SendDataToClient( player, ... )
{
    if( vargv.len() > 0 && vargv[0] )
    {
        local byte = vargv[0],
              len  = vargv.len();

        if( 1 > len ) Message( "ToClient <" + byte + "> No params specified." );
        else
        {
            Stream.StartWrite();
            Stream.WriteByte( byte );

            for( local i = 1; i < len; i++ )
            {
                switch( typeof( vargv[i] ) )
                {
                    case "integer": Stream.WriteInt( vargv[i] ); break;
                    case "string":  Stream.WriteString( vargv[i] ); break;
                    case "float":   Stream.WriteFloat( vargv[i] ); break;
                    case "bool":    Stream.WriteBool( vargv[i] ); break;
                }
            }

            if( player == null ) Stream.SendStream( null );
            else if( typeof( player ) == "instance" ) Stream.SendStream( player );
            else Message( "ToClient <" + byte + "> Player is not online." );
        }
