Ok I get it.
First you need to see it as used one in auto scrap market, possibly Rawalpindi or Peshawar.
If you can't find, I have an idea. But for that, you need to have some knowledge of electronics. Or take help from professional/electrician friend.

1) first you need to open the box (having writings on it). Observe the copper probes polarity which are broken (very important).
2) only then, cut the green n white wires.
3) check polarity between the two wires (green, white) and the two copper probes. After that you will come to know which wire need to be connected to which probe.
4) Connect/solder the wires with probes, secure them with hot glue or epoxy resin.
It is quite hard but not impossible.
