Off the top of my head; There's a mild difference between 90-93 and 93-95 looms, I can't remember what but I'm sure someone will point it out, nothing major though I don't think.
I used the back of the blue haynes manual for the Polo and found it fairly easy. I created a table of cable colours and locations and connections but can't find it now. I think I may have posted it on here years ago, or PSD.
The pumps are different, but only the inline pump? All lift pumps are the same, but the inline ones get swapped dependant on pressure required in the lines.
Feel free to correct me people, I am hungover
