LD150 mk3 Parking light

Hi!
I have a question about the parking lights on an LD. I have a new battery, and I have the rear light working when I choose "1" on the light switch, with the bike off the rear light switches on. But not the front light, should the front light work too? I realised that in the lamp assembly I am missing one cable (as there are 4 slots and I have only 3 cables connected) so I am guessing that's why the front light isnt switching on too? How should I wire that cable?? I found the diagram but cannot really see where that cable goes? Thanks for any help provided in advance!!
