Electric steering column, need help please!

[Jimmi The Kid]

I head some one use a Opel/Vauxhaul Corsa electric steering column. Can anybody tell me witch model and year they use, and which parts I need???
I think I need some electronics to controle it.
Some pictures will also be great

I allready have a Toyota Yaris NLP90 electric column, but I don't think it will going to work, because I can zero-point calibrate it, without it fitted to the vehicle. It run with a CAN-BUS system, so I can't use the steering ECU by itself. It have to be connected to the whole system

I talked with some guys from the Danish Touringcar Championship, the had electronic steering column in the Corolla E12. They ran in some problems when they hit the curbs, then the powersteering went off! They actually had to get a new software from the developer in Japan, and I don't think I afford such thing

I will use my AE86 on the tracks, so I had to know if the Corsa steering column have the same problems.
