96 mk1v non turbo wiring diagram and looking for heater matrix Ali inlet/outlet pipes

Hi all, could some one help me find the wiring diagram for my mk1v 96 non turbo manual especially the bit that goes to the heater box as I can't see which elec plugs are holding it in, I was changing the heater matrix but have found the last person that did it have bent the inlet and outlet. Ali pipes and have leaked from there so am trying to source these parts too, but need to get the whole unit out thanks in advance oh ps I have looked at a few threads but with no joy on the links or any advice is much appreciated
