Hi Gary - I've converted my 1998 Abbey to a continental style 13 plug to suit the socket on my Bora. I made a careful note of the original wire colours and where they were connected to inside the front of the caravan, from the van instruction book I was able to identify their function. You then need the C C leaflet to identify the correct wires in the 13 core cable, but note that around 1998/1999 there was a small change in the wiring set-up, so check out your van carefully. When wiring the new plug to the cable be meticulous with the length of wire stripped and take your time - it is a rather fiddly job but not impossible! Good luck.
