Td5 90 diagnostic plug

Hi apologies I’m new to this, I was wondering if anyone can help me I have a 2000 Td5 90 that I am in the process of re building and we noticed that the previous owners had cut the diagnostic plug off between the seats for some reason. I don’t know anything much about the electrics on a landy and I’m wondering can you just buy a section of the loom or do you need the whole thing and does anyone know where I can get one from

Thanks for any help
