Golf 3: Pump Düse Conversion Guide

hi

I'm currently in the process of converting my Golf 3 to a 1.9L TDI PD engine from a Golf 4, with 100 horsepower.
The engine is already installed!
What about the electrical system? Where can I find a suitable wiring diagram?
What should one consider regarding electrical work?
Do I have everything I need, like the speedometer, etc.?

Best regards,
micha

Hello,

It's obviously great that these questions weren't clarified before the renovation.
Well, you can actually buy the wiring diagrams. The dealership usually has a few file folders for each vehicle with repair guides, etc. A more sophisticated approach would be to use specialized software.
