Just a heads up, the original headlight are wired via the ignition switch so all of the current goes through the contacts in there. If you increase the headlight globe wattage or add extra load with auxiliary lights you will shorten the life of the ignition switch considerably. Been a problem for a long while as everyone wants better lights.
The best way is to use the feed to the lights to control a relay (or 2) and then run a new fused cable from the starter motor battery connection to the relay and power the light from that. That will take the load off the ignition switch. The headlight relay itself switches between high beam and low beam so if you have 2 other relays you can just power the coils from each fuse for high and low beam. There are separate fuses for high beam and low beam, the top of Fuse 3&4 (linked) are the low beam relay output and the top of 5&6 (linked) are the high beam output. You should be able to run a wire with a spade connector from the bottom of one of each pair and that will give you a fused feed for operating the relay.
You can also mount the relays in the spare sections under the fuse box and use spade connectors to connect to the relay which will hold it in l=place. can be a bit fiddly but at least all the relays are together then.
Hope that helps.
