Nope - not positive and negative - these are balanced data feeds, which are labelled at (+) and (-) for the two "poles" of the data feed.
X18802 goes to the nav unit at the back of the car (A112) and connects via X1313: -

The relevant pins on X1313 are 5,6,7,12,14,15 &16.
No idea what "data" these three data lines carry...
