Ordering a recon steering rack - Offered two types

Hi Folks

I'm after some advise on which steering rack I need.  I called Western and ACS today and both stock two types for the Skoda Fabia.  Both informed me to look at the steering angle sensor and tell them if it was brown or white.  Well after much crawling around under the car, from what looks like to be the sensor, it's neither of those colours.  It just looks to be black like all sensors.

Can anyone advise what would be fitted on a 2004 Fabia VRS?  My slow fluid leak has turned into a significant pool on the floor after a few hours leak so want to get a rack ordered and fitted ASAP by a local mechanic.

Thanks in advance...
