Hey,

I got myself a cheap pair of A4 B7 bixenon ballasts ("bosch 1 307 329 115 098 121 129" was mentioned by the seller), without any wiring. I'm looking to fit these into my B5 (probably not under the headlights..).

First of all, is this even possible? Are these units too smart to run without something telling them to run? I was hoping I could just give it power and it'd work. Also wondering if these units are all I need, or is there another pair of components (igniters?) involved.

Can anyone point me to a wiring diagram / pin out of these units? Not gonna go poking around HV myself. Are the connectors sold separately somewhere?
