I'll dig out the schematics from Elsa later as reinstalling desktop, but it does say the steering ecu pin on the RT wiki, check your steering ecu to see if that wire is already present, also on the A3 the wire goes to the area by the wiper motor/plenum because it is present from the main ecu to a connector under that area.
Here is some more info from an AS thread to read in meantime.

Didnt your cruise kit come with the full guide as most kits do have a guide which are usually very good or did you buy the loom seperately from the stalk & get stalk from VW?
Does the wire you have have the correct pins on the end or is it bare wire, also how long is this wire cause this would help determine if its same location of the A3, same platform so shouldnt be far of, but for sure when I get into Elsa later I can confirm this.
Thank you very much for your reply..
Mine is a 55 plate car so should be OK,
I can't check the wire is currently there, but will get the technician who installed the stalk to check, he's also going to stick in another control module to see if that fixes the issue, but i don't want to have to go spending £130 for a control module when fitting the wire would have cured it.
The stalk came with a guide but the technician lost it when he was fitting the stalk, so now i don't have it... i'll see if i can get it back. The wire came in the kit with the stalk and instructions.
Yes, wire has the correct pins pre crimped on the ends. Its 89mm long
Thanks,
