Okay I have had a major breakthrough, on the back it showed the pin numbers (which I hadn't seen till now)...left to right, 15,16,1.....14. Therefore it was wired up wrong, but it is a strange pin config. I have wired it up properly and now the PIC transmits the signals and the LCD receives them. There does look to be life from the LCD but it seems to fade out after a few seconds. Both the PIC and LCD are warm now though so that shows communication atleast.
