I'm not an electrical expert so maybe one will step forward. However here is my opinion for now.
I can't remember what I used but my thinking would be max load on feed wire from battery to relay is two 60 watt bulbs. So 120 watts at 12 volts = 10 amps. From the "Vehicle Wiring Products" web page (earlier link) that would suggest using 28/0.30mm standard type cable which has a continuous rating of 17.5 amps. You could use a smaller wire size for the rest as each individual bulb is only taking half that load. The bulb holders I got had the wires attached and may have been a small size, but then they are only taking half that load each. No harm in using the thicker wire though.
I don't know what the operating current of the relays is but it will be much less. i.e. the green/yellow and the black/yellow on the wiring diagram.
