That matey matey wiring loom is only an uprated loom for the dip beam...
There are details about a 3 relay wiring loom that uprates the dip beam, main beam and spots/fog lamps.
Really all you would need to do is to wire up 3 relays using the diagram matey matey has supplied but wire up three relays so that the dip and main bean cut each out when you move the stalk and as for the spot/fog lights, in essence its the same loom as above but use the fog lamp signal from the stalk to switch the relay on.
