I’m fitting a pfjones 7 pin wiring kit. My t6 doesn’t have tow bar prep and is therefore option 2 in the wiring instructions. That’s probably irrelevant because - I’ve remove all the lower dash under the steering wheel and it says there is white can data and a black network control to wire into but I can’t see either. Photo of the items attached from the instructions but I can’t see them. Are the always fitted? If so are they always under the dash. Anyone with some words of wisdom who has fitted pfjones wiring would be much appreciated
