Going to mount some Extra driving lights on my Fabia -16, anyone here knows wich cable is + to original highbeam?

This I would also like to know!

Be very carefull with wires.. The whole lightning system in these cars is PWM driven. Do a little research before splicing the wires. 

Also the voltage levels and brightnes can be altered using VCDS. It is originaly not turned all the way up. 

For longer bulb life.

What information would I be looking for, precisely?

How to properly attach a relay to this kind of system and how to assure that a relay will not klick (flicker) due to nature of PWM (pulse width modulation) power supply. If this will produce any errors on the CAN bus and so on... Probably you are not the only one that wants to do this. 

That´s what I´m hoping to learn here! :-)

Do your research like others have... I just wanted to tell you that it is not that straight forward as in the old analog times...

Oh, that´s nice. Thanks!

Pretty sure there are CAN-bus adaptors that can turn the lights on/off by listening for the right CAN-bus message too.
