as far as i know you dont need any special relay, you just need to have the relay active when there is accessory power to it

so its a little thing with 3 plugs 1 and 2 are the circuit and the 3 is a signal and it probally grounds it self, maybe a 4th for the ground, but still its not the relay that i have seen in the at the shops, the ones i saw had about 6 - 10 plugs,

So I cant understandf what do you actualy want to do:

A) Have the headlights shine brighter or
B) Have the headlights go off when you turn the ignition off?

If its brighter headlights than a relay might be of dubious benefit without converting to hallogen headlight units and upgrading the wiring - then you could either use a pair (one for low and one for high beam) of standard 30amp auto relays or the special twin headlight relay by "New Era" from Supercheap auto - there was a guide written for doing this - do a search.

If you just want the headlights to be ignition dependent then the wire than supplies the +12v to your headlight switch is either fed from the ignition switch itself or from the un-fused side of the fusebox (depends on age of car). Just swap it over either to the always on terminal on the ignition switch (clue it'll be the same terminal set as the thick brown wire +12v feed to the ignition switch) or to the always on terminal on the fuse box and done.

nahhh - the standard headlights with relays work really well - I got sick of driving by candlelight and got a couple of $6 relays from Jaycar..... awesome now with the same lights

I measured the voltage at the lights when powered through the switch - 9.75V, with the relays, 12.5V+..... those 3 odd volts make a huuuge difference to the lights!

all you do is mount the relays near the starter solenoid, take the power from there and hook it up to one side of the relay, the other side goes to the lights, and the existing headlight switch wire goes to the switching input of the relay - job's done!
