Yo mate,

first things first: The idea is there, so you have my input.

How to solve the functional question, tecnically?

I guess, there is running power to the drive and there is data comming from the drive.

Maybe someone has the technicel scematics of a MK4 unit and someone knows how to convert it to standarised IDE, PATA, SATA, SCSI or USB.

We are all car lovers, but I hope there is a genius among us
