Yaris 2003 1.0 (VIN V) - Power Steering Installation: Parts, Costs & Assembly Guide

Hello.
I have a yaris from 2003. Vin starts with V (not J)
I would like to install a booster in it. Some write that it costs PLN 2000, on the other hand, the auction site has a set for PLN 520, and assembly instructions for PLN 40.
Can anyone comment on what parts he needs and what the plus minus assembly looks like?

It's not that simple, because there were two versions - hydraulic and electric, but I can't tell which one is which.
Also write where the car was produced, because it differed depending on the market. Maybe someone will tell you.

V is France, J is Japan.

It should be electric. Approximately - mechanically, there will be no major problems, but it may turn out that after connecting it will not work or will not work properly, because the version without power assistance may have different wiring harnesses. I'm not sure if the steering column is the same in both versions - probably not. Perhaps those who offer for a few hundred zlotys make a sculpture with the addition of power steering to the existing system (the system will not be factory) - I do not know. The price should not exceed thousand, the 2000 is probably someone pulled out of space, but there are also magicians. Or maybe on new parts from ASO.
